After seeing the emotion color, they all turned pink.

Chapter 258 Xu Chuan's Best Friend Real-world Application of Probability Models

other people?

There are no strangers here, Xixi, they're all family.

"walk slowly."

Xu Chuan nodded.

Beside her, Princess Xixi, having received an affirmative answer, smiled with satisfaction.

The faint red tinge of anxiety in the outline of the girl's emotions gradually dissipated, and she transformed back into the happy Princess Xixi.

The bus heading to Jiangting University, the first stop on the study tour, started and drove off.

After resting and recuperating at the hotel for a while after lunch, the students were much more energetic when they got back on the bus.

"Beep, beep..." The little bee's tuning sound rang out.

Immediately afterwards, the female tour guide's energetic voice rang out.

"I hope everyone has rested up by now. I see some of you are already playing games online... You can play online games anytime. When you get back to the hotel tonight, you can play however you like. Since we're on a study tour, I hope everyone can focus on the journey..."

The tour guide, Ms. Xiaohua, clapped her hands and continued with a smile.

"Our first stop this afternoon is Jiangting University. It might be a bit far, but Teacher Xiaohua has prepared some games for everyone. Feel free to participate..."

The words failed to liven up the atmosphere inside the bus.

It just made the voices of the classmates who were playing online games together a little quieter.

It's obvious that Hanako is no match for the engineers from Tencent and NetEase games.

"Everyone, please participate! I specially brought Teacher Xiaohua to this car. In that other car, Teacher Liu is probably playing English situational dialogues with them right now..."

Zhou Min, who was sitting in the front row, spoke up.

The homeroom teacher's role played a crucial role.

But what truly attracted everyone's attention was the stack of cards that the female tour guide pulled out of her bag.

The tour guide, Ms. Xiaohua, smiled and held up the card in her hand.

"Let's play Truth or Dare! Everyone who participates will receive a prize!"

"Um?"

Li Jiaxin, sitting in the first row, seemed to have extracted some key information and suddenly perked up her ears.

She turned off her phone and snapped out of her reverie, immersing herself in a gay novel.

"Sure, sure!"

I started to show my support.

The other students on the bus were clearly interested when they heard about the game.

As the crowd's emotions were outlined, a sense of euphoria gradually emerged.

"Haha...it seems everyone likes it. So...is anyone volunteering?"

The female tour guide was very satisfied with the atmosphere and began pacing in the aisle of the carriage, looking for volunteers.

However, whenever she approached a seat, the students would shrink back and wave their hands repeatedly.

The essence of Truth or Dare lies in having fun and joining in the excitement; everyone just wants to be a spectator.

When the female tour guide approached Xu Chuan's row of seats, Lin Xixi also turned her head away and shrank back into the seat...

Judging from her appearance, it's clear that her trip with Gou Jiaxin last time left her with deep psychological trauma.

But this time, there's really no need to be too afraid.

From the moment the female tour guide pulled out the card to the moment she searched for people back and forth in the bus aisle, her emotional state remained perfectly normal.

There were also some blues that seemed a bit down because no one was willing to participate...

This was a study tour organized by the school, and the tour guide was a licensed student guide.

Therefore, the truth or dare cards in the tour guide's hand must all contain wholesome and normal content, completely different from Gou Jiaxin's...

Xu Chuan guessed that the most pink question inside was at most:

Please name your favorite teacher at school and explain why.

"Nobody's willing to participate, so I'll just pick someone."

After walking around in circles, no one was willing to take a card, so the female tour guide used her last resort.

"Who's the squad leader? Is the squad leader on this bus?"

"ah--"

Lin Xixi shrank her neck, let out a mournful cry, and looked at Xu Chuan with a pitiful expression. "Why—"

The girl pouted slightly, her clear, watery eyes filled with pleading: "Help me, help me..."

This is fucking... a little too cute!

"The class monitor is here!" Xu Chuan raised his arm, pointed to the seat next to him, and immediately notified the tour guide...

"?"

Princess Xixi didn't even react, and was stunned for two seconds.

She admitted that she had a little bit of a cutesy act on her part... but Xu Chuan just blew me away like that?

Did he even look at it properly...?

Meanwhile, the tour guide was overjoyed.

She walked over with the card in her hand, first looking at Xu Chuan, and then at Lin Xixi, whose face was slightly flushed.

"Wow, the class monitor is so pretty... the class beauty..."

The female tour guide laughed in surprise, truly stunned by Princess Xixi's beauty.

"No, no..." Lin Xixi waved her hand, composed herself, and replied with a slightly embarrassed smile, "I'm not..."

"You misspoke, you mean the school beauty, right? Haha..."

The tour guide continued jokingly, "Come on, pretty girl, draw a card..."

After saying that, she rubbed the card in her hand and handed it over.

"After you draw your question, read it aloud before answering it..."

"Um……"

Lin Xixi drew a card from the deck and looked down at it.

I was a little nervous at first, but when I saw what was on the card, the tense purple underlined in my emotions immediately disappeared.

Please name your favorite animal.

"Please tell me your favorite animal..." Tour guide Xiaohua handed the microphone of the little bee to Lin Xixi's mouth so that she could reply amplified so that all the students in the carriage could hear her.

"My favorite thing is... rabbits..."

"Rabbits are so cute! By the way, you might see one this afternoon on the Jiangting University campus. They're just really fast, so it's hard to touch them..."

"Ah, really?" Lin Xixi looked at Teacher Xiaohua, her face filled with anticipation and curiosity.

"Yes, several campuses have them, the little white rabbit..."

The tour guide smiled and replied, then reached into his bag, pulled out a small item, and handed it to him. "This is a prize."

"Thank you, teacher."

After a polite reply, Princess Xixi accepted the prize.

It's one of those trendy acrylic commemorative tags: "I miss you so much in Jiangting..."

"Who's next... who should I pick next... hmm..."

Xiaohua held the card in her hand for a moment, looked around, and then asked a question.

"Was the top student in our class on this bus last time? Who was it?"

"..."

"he!"

As if in retaliation, Lin Xixi raised her arm, pointed at Xu Chuan beside her, and shouted.

However, perhaps because she was a little too excited, her shout just now was quite loud.

After shouting, Princess Xixi felt a little embarrassed. Her ears turned red, and she leaned back and shrank back. She pursed her lips and smiled at the tour guide who had walked around, this time speaking softly.

"he……"

"Oh...what a coincidence, we're even sitting together. That saves me a couple of steps...Here, draw a card."

"..."

Xu Chuan also reached out his hand.

He pulled out a truth-or-dare card from the young tour guide in front of him, whose emotions were already overflowing with pink.

"May I ask... who is your best friend in class?"

Hey? Why am I being asked such an embarrassing question?!

What's wrong with the author?

Xu Chuan held the card in his hand.

But before he could speak, Lin Xixi, who was sitting next to him, spoke first.

"Jiaxin, or Li You..."

Her voice was neither too loud nor too soft; everyone around her, including the tour guide Xiaohua, could hear it.

To onlookers, this sounded like Princess Xixi making a wild guess...

But in the emotional outlines that ordinary people cannot see, Lin Xixi's body has already been outlined with a lot of tense purple, and a little bit of sad blue.

Her words were both a reminder to Xu Chuan and a way to protect her own self-esteem.

First, state the most likely answer yourself, thus indirectly confirming it for others and even for yourself.

She wasn't troubled by whether Xu Chuan would consider her his best friend.

Although... there was indeed a secret expectation in my heart.

I hope Xu Chuan will say that she is his best friend.

However, this expectation held too little weight in her heart.

It was even less than her concern about whether Li Jiaxin and Xu Chuan were in a difficult position.

On this bus, she really wanted Xu Chuan to say "Li Jiaxin," not wanting Jiaxin to be disappointed, nor wanting to put Xu Chuan in a difficult position...

So let her take the initiative to back down and speak up.

"His best friend is on another bus, and so is that girl in front of him... Jiaxin..."

"Ah...ah..."

The tour guide was somewhat surprised.

Surprisingly, the cute and pretty girl who had just answered the question actually volunteered to answer it for the boy.

It's a bit subtle...

And also... why does it feel like...?

Her smile didn't seem so happy...

"Haha, in another car... And you said the student in front? His name is..."

"And this one, she is too."

Suddenly, Xu Chuan spoke.

The tour guide hadn't even finished speaking when he was abruptly interrupted.

Xiaohua's gaze had already shifted to the front of the bus,

I'm getting ready to find the girl named Jiaxin, who's known as this boy's best friend.

But now, the focus has shifted back.

In her field of vision, Xu Chuan was holding the Truth or Dare card, looking up at her with a faint smile, but his hand pointed to the side...

He pointed to the lovely girl sitting inside him at that moment.

"..."

I'm a fan of the female tour guide.

Lin Xixi, who was being pointed at by Xu Chuan, was completely stunned, as if she had been frozen in place.

"Ah, that's perfect..."

The tour guide smiled and put away the truth card from Xu Chuan's hand.

Who is your best friend in class?

The purpose of this card is actually to introduce a warm-up game, a test of teamwork with good friends.

Its original intention was not to force anyone to choose one person from several friends.

Therefore, Xiaohua is quite satisfied with the current situation, even more satisfied than expected...

You're absolutely perfect!

"Here, this is for you."

The tour guide gave Xu Chuan an acrylic commemorative plaque that was the same as the one Lin Xixi had won by answering questions earlier, as a prize for participating in the truth or dare game.

Then, she clipped the little bee to her pocket and took out three small plush toys from her bag.

A little brown bear, a little orange cat, and a little crocodile.

"We have a little game to test the teamwork between good friends. It's just the two of you, you're sitting close together so you don't have to move. The prize is a small plush toy to choose from..."

Xiaohua pushed the three toys in her arms forward and asked with a smile.

"Want to give it a try?"

"Are you coming?"

Xu Chuan turned his head to look at Lin Xixi.

"Hmm? Hmm..."

Princess Xixi seemed to have become a little silly. She was just spacing out and didn't know what she was thinking. She only came back to her senses and nodded after being asked.

"Okay, let me explain the rules."

Xiaohua gathered the three dolls in her arms closer together, and to make it more fun for more classmates, she turned up the volume on the little bee's microphone.

Then, she gave Xu Chuan and Lin Xixi each a piece of paper and a pen, and continued.

"Here I have a bear, a kitten, and a crocodile. Each of you choose your favorite and write it down. If you both choose the same one, then you can have the toy for free..."

"..."

I have never seen such a wonderful match.

【Little Bear】

Xu Chuan wrote it down.

【-】

Lin Xixi hasn't written it yet.

But seeing how quickly Xu Chuan wrote, she was now caught in a dilemma.

If only I could foresee the future and see what Xu Chuan was writing...

All three dolls are very cute.

However, I seem to remember Xu Chuan mentioning before that he has cats at home.

Moreover, the porcelain souvenir he brought her back from the exam at No. 3 Middle School last time was also a cat...

Does he really like cats...?

But among these three plush toys...

She actually preferred the goofy little bear.

Which one should I choose?

Which one will he choose?

……

Why are you still hesitating?

Xu Chuan started to panic.

Just now, he casually scanned the scene with his emotional vision and noticed that when Lin Xixi was looking at the teddy bear, the pink color in her emotional outline increased significantly.

There's no doubt that Princess Xixi likes that teddy bear.

and so……

Is she just guessing what he likes?

You're always thinking about others, Princess Xixi.

"Wait, I'd like to increase the difficulty..." Xu Chuan raised his arm and gestured to the tour guide, Xiao Hua, beside him.

"Um?"

The tour guide paused, seemingly a little confused, then smiled. "Increase the difficulty? What do you mean?"

"We want two dolls."

Xu Chuan pointed to the three dolls in the tour guide's arms and then said.

"How about this? We'll each take a picture of the three dolls in order of our preference, and write them down on a piece of paper. If the final order matches, we'll get an extra doll as a reward..."

"Huh? This... this is how you play it?"

Xiaohua was surprised.

This was the first time she had ever seen it. Actually, the odds of winning with the previous selection methods weren't very high.

"Haha, that's great!"

Suddenly, Zhou Min, who was sitting in the front, spoke up after hearing what was happening.

As a math teacher, she laughed.

"A question from the audience: In an ideal, completely random scenario, what are the probabilities of winning using the methods Ms. Xiaohua and Mr. Xu Chuan just mentioned?"

"ah--"

The crowd groaned in dismay. "How come there's math here?"

In an ideal situation,

Without prior communication and without knowing each other's preferences,

Each person chooses according to their own preferences; it's essentially a random selection.

The original plan, Xiaohua's suggestion of a tacit understanding challenge, was a classic "choose one of three" scenario.

The probability of winning is 1/3.

But Xu Chuan demanded more rewards and then forcibly increased the difficulty.

This becomes a problem of matching probability in random permutations.

The original success rate was one-third.

Now, if it's still random, then the two people need to have the exact same ranking of their doll preferences.

There are 3! ways to arrange the three dolls.
