People are betting wildly, ten consecutive guarantees

Saotome Mea Ari also knew that Ayanokouji was doing it for her own good. Seeing that Ayanokouji did not stop her, she was also relieved, and returned a bright smile to Ayanokouji: "Trust me, I can win!"

Ayanokoji Kiyohei and Huang Quanyue Luna arrived in time, and the betting hadn't started yet.

Although Meikuliang didn't know why she didn't like Ayanokoji Kiyohei, but at the request of Jule Sachiko, she still informed the two of the rules of gambling.

The game they are about to play is called [Three hit dice]. The rules are as simple as the name of the game. The dealer, that is, Mikura, throws the dice.

Among them, one point, two points, and three points are regarded as "Down", and four points, five points, and six points are regarded as "Up". The two need to guess whether the dice will be up or down when the dice are thrown three times in a row.

Both parties wrote down the results of their guesses on paper, and then handed them over to the croupier Mei Jiuliang.

She will keep rolling the dice until the first guess wins.

The rules of this game are not complicated. For the sake of easy understanding, an example is given by flipping a coin.

To put it simply, it is to guess the front and back of a coin, with heads being up and tails being down.

For example, Saotome Yari guessed [UUD], which is [up and down].

If the croupier Mikura tosses the coin three times in a row, all are heads, and on the fourth time she tosses down, that is, when [Up Up Down], there is Saotome Meyari's guess, then Saotome wins The gamble wins.

If it doesn't come up, then she will continue to throw until one of the predicted results comes up.

Regardless of whether it is a coin or a dice, the probabilities of heads and tails are the same if the props have not been tampered with.

The probability of heads and tails is one-half, three heads in a row, the probability of occurrence is one-eighth, three tails is the same, the probability is one-eighth.

There are a total of eight possibilities, and the probability of occurrence is the same. It doesn’t matter what you write—in people’s common sense, they all think so.

But in fact, this is the content of classical probability, which is always used in people's common sense to solve problems.

Classical probability, also known as prior probability, refers to the probability that various possible outcomes and the number of occurrences in a random event can be known by deduction or extrapolation, without any statistical experiments. probability.

Simply put, classical probability is an equally likely concept, such as rolling dice and flipping coins.

In classical probability theory, if there is not enough evidence to prove that the probability of one event is greater than the probability of another event, then the probability value of the two events can be considered equal.

However, a series of problems in real life cannot be explained by traditional probability definitions anyway.

It's like this gambling game right now.

No one can be sure that the coin and the dice are "perfect", that the dice are made evenly, that their center of gravity is in the exact center, that the roulette wheel is leaning toward a certain number, and that the dealer's hand is affecting the center of the dice or coin.

Therefore, if you simply think that this is a problem of calculating probability, it is a big mistake.

This is actually a classic mathematical expectation problem in probability theory.

When Qinghei Ayanokōji was in college in his previous life, he often solved this type of questions. When Mei Jiuliang said this rule, he began to calculate his expectations in his heart.

There are many ways to calculate expectations, so I won’t list them here, and just put the results directly.

The expectation of the two probabilities of [Up Up Up] and [Down Down Down] is 14.

The expectation of the two probabilities of [up and down] and [down and down] is 10.

The expectation of the four probabilities of [up and down], [down and up], [up and down], and [down and up] is 8.

In other words, the following four arrangements are more likely to appear first. If you want to guess, you can just write down any of the following four arrangements.

Of course, no matter how unlikely other permutations appear, there is still the possibility of them appearing.

After all, it's still a game of luck.

Text Volume 46: Chapter [-] Saotome, Defeated

Both Saotome and Togakushi Yukimi have already handed over their answers.

Ayanokōji believed that Saotome Mea Ari, after all, she had studied hard for several years to be admitted to this school. Although the probability problem was a bit out of the ordinary, she should be able to solve it.

Moreover, there are other ways of thinking than expectations.As long as Saotome thinks about it for a while, she will definitely choose one of the four answers.

As for Togakushi Yukimi, Ayanokōji Kiyohei is not familiar with her, but she also looks like someone who has read a lot of books. I am afraid this question will not trouble her.

In other words, in the end, it still depends on luck.

After confirming the content written by the two, Mei Jiuliang turned it over and put it in his hand, and began to bet.

"The first round is...the next."

"The second round is ... on."

"The third round is... the next."

A probability has appeared, Mei Jiuliang has already seen the arrangement of the two, since she has not stopped rolling the dice, it means that neither of them wrote this arrangement.

Saotome let out a breath of relief, took out a thermos from her schoolbag, drank a sip of water as if trying to keep calm.

Her water glass has a cartoon spotted pattern and looks like it has been used for a long time, with many white marks on the glass.

"You still have a water glass." Togakushi Yukina didn't miss this opportunity to hit Saotome Mea Ari: "You have used this glass for a long time, and you are not even willing to change it. How dare you take 100 million yen to gamble?" ?”

"Can't I be nostalgic!?" Saotome Mea Ari replied not to be outdone, and glanced at Ayanokouji, as if she was shy when he saw his rustic side, and quickly put away the cup.

"It's not the time to care about this!"

Ling Xiaolu looked at her as if she was looking at her own unsatisfied child: "I'm gambling now, you should concentrate."

"Yes......"

Saotome smiled sheepishly, shifted her gaze to Meikura, and watched her throw the dice seriously.

Even so, she couldn't change the result of the dice, after all, she could only watch dryly.

Mei Jiuliang seems to be used to the role of dealer, she rolls the dice very regularly, every time the dice almost always fall to the same point.

The dice were thrown six times quickly, Saotome Meyari and Togakushi Yuki saw that neither of them made a sound, and stared at the dice with tense expressions.

"The seventh round...on."

Saotome was still waiting for Meikura to cast the eighth, but at this moment, she stopped.

"The game is over, Yukino Togakushi has won." She turned over Yukino Togakushi's card, which said [DDU], which means down down up.

"Eh?"

Togakushi Yukimi and Saotome Mea Ari were taken aback.

Is this the end?

Saotome Mea Ari hasn't reacted yet.

If I lose, my 100 million yen will be wasted like this?how so......

"According to the previous regulations, the ownership of the casino belongs to Togakushi Yukimi, Yari, you owe me 25 yen."

Jule Sachiko looked at Togakushi Yukino, she seemed to be overly shocked, her pupils constricted, and she looked at her card with [DDU] on the table in surprise.

"What's the matter, Togakushi, you won, please be happy?" Jule Sachiko smiled, "What's the matter, do you have any questions?"

"No...!" Seeing that she had just woken up from a dream, Hu Yinxue quickly shook her head, with some uncertainty in her tone: "I can continue to use this room, right?"

"That's right, you and the student union's debts have been written off. However, if you default on the venue fee next month, we will come again."

Mei Jiuliang approached Togakushi Yukino, with a gloomy expression, as if threatening: "You won't be in arrears with the venue fee anymore, right?"

"No more!" Togakure Xuejian seemed to have finally realized that he was guarding the casino, his face brightened suddenly, and he cheered: "Great, I won! There is no need to pay back the venue fee for the student union! "

Unlike Togakushi Yukimi's cheering, Saotome Mea Ari on the other side had an ugly face.

"Mea Ari..." Compared with the 50 yen he lost, Hanade Katsura was more nervous Saotome Mea Ari, "Are you okay...?"

"...I'm fine." Saotome Mea Ari shook her head, stood up and begged Jule Sachiko, "Jule-senpai, can you give me another chance?"

Xingzi Jule tilted her head and asked curiously, "Why, do you still have money?"

Saotome Mea Ari was silent, shaking her head slowly.

"If you don't have any money, don't even think about gambling. It's good for you." Jule Sachiko yawned as if feeling bored, and reminded softly: "By the way, remember the 25 yuan you owe me?" Delivery to my office tomorrow."

"Do you want it tomorrow!?" Hua Shoumao exclaimed in surprise, "This is too urgent!"

"Who told you that you didn't say the deadline for the return, so I can only say a time that is convenient for me." Jule Sachiko jumped off the desk with a light leap, took the iron chain in his hand, and was about to pull it. Mei Jiuliang leaves.

"The good show is over, so I'm leaving too..."

Huang Quanyue Luna stretched her waist, turned around and smiled at Ayanokoji Kiyohei: "By the way, if you still have something to eat, you can find me in the lounge of the student union!"

Huang Quanyue Luna still couldn't forget the taste of that bag of potato chips.

Several people were about to leave, and Ayanokouji Kiyohei was also about to leave.

"Wait, don't go yet!"

Ari Saotome suddenly yelled, attracting everyone's attention.

She left from the gambling table, stumbled towards Qingping Lingxiaolu, and said eagerly: "Lingxiaolu, lend me some money, I can win it back! I will definitely win the next round!"

Saotome Mea Ari wants to borrow money from herself... Ayanokōji doesn't think it's unusual.

Now she is completely a gambler's mentality - she thinks that she lost the game because of bad luck, as long as she does it again, she will definitely be able to come back.She's willing to risk anything for a desperate...

Saotome took Ayanokoji's hand and continued to pray: "No matter how much you win, the final money will be given to you! Lend me 100 million first!"

Ayanokōji sighed softly, and pulled away Saotome Mea Ari.

"I understand what you are thinking. You think that you lost this time only because of a small probability event, as long as you come back next time, you can win. But have you ever thought about what to do if there is another small probability event? You should How to repay this large sum of money?"

She owed the 25 yen to the student council, and Ayanokouji could help her with it first, but Ayanokouji Kiyohei was not going to lend money to Saotome Mea Ari for gambling.

He hoped that Saotome could calm down and taste the bitter fruit of this failure.

However, Saotome Mea Ari didn't seem to want to think so.

Seeing that Ayanokouji Kiyohei didn't lend her money, everyone was about to leave. Saotome Meaari was anxious for a moment, and directly rushed towards Ayanokouji, putting her whole body's center of gravity on him.

Ayanokōji was caught off guard for a moment, and was crushed by Saotome Meari.

Fortunately, the floor of this room is covered with soft sound-proof carpet, and he was not injured.

Ayanokouji felt a little dissatisfied, what is Saotome doing, even if she doesn't lend her money, she can't hit people...

Ayanokōji looked up and saw a pure and lovely face occupying his entire line of sight, Saotome Mea Ari was bending over him in a very seductive posture, staring at him eagerly.

Feeling the softness of being close to him, Ayanokōji did not waver in the slightest, when he was about to scold Saotome loudly, he saw her boldly leaning down in front of everyone, and put her face next to his ear .

"That guy Meikura cheated, give me another chance, I can win!"

Saotome Mea Ari whispered anxiously in Ayanokouji Kiyohei's ear.

Text Volume 47: Chapter [-] Saotome's Way to Win

Meikura is cheating?

Hearing these words from Saotome Mea Ari, Ayanokouji was neither surprised nor surprised.

Ayanokouji was not surprised that someone would make a move.

In a place like a casino, if there is no prior regulation saying that you cannot give up money, then it can be concluded that giving money is almost an inevitable behavior.

In particular, the student union's punishment for cheating is very small, almost reaching the level of encouraging others to cheat, and it will be strange if no one cheats.

What surprised Ayanokōji was that, according to Saotome Mea Ari, the one who made the move was Meikura, the girl with the collar around her neck.

Mei Jiuliang is like a loyal dog of Sachiko Jule, she does whatever the other party asks her to do, and always obeys Sachiko Jule's orders.

Could it be that Sachiko Jule instructed her to let Saotome lose?

Why?It's not necessary at all.Sachiko Jule wouldn't covet Saotome's 100 million yen, would she?

Ayanokoji Kiyohei thought of another possibility.

What if, instead of being instigated by Jule Sachiko, Mei Jiuliang decided to cheat Togakushi Yuki to help Togakure, but Jule Sachiko acquiesced in her actions?
