Ten Days End

"Oh?" The pig was a little confused, "I don't understand what you mean."

Old Lu was also a little confused: "Boy, what are you talking about? Is there a "sure way to win" in this game? "

"I dare not say the sure way to win." Qi Xia shook his head, "But "Pig Games" are definitely not "luck-based" games, but "probability" from beginning to end."

"What do you mean?" Old Lu was a little confused, "No matter how you distribute them, the number of black and white pieces is 50, which means that the probability of you touching all the pieces is one in two."

"Really?" Qi Xia shook his head without comment, "It is because of this that this game looks close to "luck-based."

"To tell you the truth, boy." Old Lu leaned close to Qi Xia's ear and whispered, "The first time I separated the black and white pieces, so that as long as I could pick the bowl with the black pieces, I would win, but unfortunately I lost. The second time I evenly distributed the black and white chess pieces into two bowls, I still didn't get any black pieces. My luck was really bad. "

Old Lu touched his chin and said, "If you think about it carefully, if the ratio is broken, each bowl will have more or less black and white chess pieces, which will be more disadvantageous for me to get black pieces. So no matter what, there is no sure win method. "

Qi Xia nodded: "It is impossible to "sure win" this game. I can only try to make my chances of winning higher."

"Hmm? Do you have a solution?"

Qi Xia did not answer, but said to the pig man: "I'm ready, let's start."

The pig man smiled, then stretched out his hand and made a "please" gesture: "Start distributing."

Qi Xia looked at the two identical bowls, and then looked at the black and white chess pieces with the same texture and touch, silently grabbed a handful of chess pieces and put them into the bowl.

Old Lu looked at Qi Xia silently, not knowing how he was going to arrange these 100 chess pieces.

Qi Xia kept picking up chess pieces and throwing them into the bowl, as if he didn't count the number of black and white pieces.

"Hey... Is this okay?" Lao Lu asked hesitantly, "Do you want to count how many pieces you have put in?"

Qi Xia didn't say anything, but just kept throwing chess pieces into a bowl.

Lao Lu and Ringo looked at each other, not knowing what Qi Xia was going to do.

Qi Xia didn't stop until he threw all the chess pieces into the same bowl.

The pig-headed man was a little angry when he saw this: "Hey, hey, hey! It's a foul! It must be distributed into two bowls!"

"I know." Qi Xia nodded, "The distribution is not over yet."

After saying that, he picked up a black chess piece from the bowl and threw it into another bowl.

"My distribution is over." Qi Xia raised his head and looked at the pig-man calmly.

"What?!"

The people present were a little stunned.

What kind of distribution method is this?

There is a black piece in one bowl and the remaining ninety-nine chess pieces in another bowl?

Lao Lu looked at the two bowls on the table, his pupils moved, and after a long time he spoke: "Great...Great..."

He understood Qi Xia's tactics.

Originally, no matter how Lao Lu distributed the pieces, the "optimal distribution" of the pieces in the two bowls was to make both of them half.

In this way, he could ensure that he had a 50% chance of touching the black piece.

But Qi Xia broke this balance.

He made the probability of touching the black piece in one bowl 100%, and the probability of touching the black piece in the other bowl as close to half as possible.

Since he had to randomly choose a bowl at the beginning, Qi Xia was likely to directly choose the bowl with the black piece. He did not need to choose the pieces from the bowl and won directly.

Even if he was unlucky and chose the other bowl, the probability of choosing the black piece was almost the same as half, after all, it was 49%

He added a layer of secret "insurance" to his victory.

When the pig saw this scene, the look under the mask obviously became a little colder.

"Are you trying to be clever with me?" The human pig's tone changed, no longer sounding so childish, but with a hint of cunning.

"Cunning?" Qi Xia felt a little funny, raised his eyebrows and said, "Everything I did did not violate the rules, how could it be clever?"

The human pig took out a blindfold from his pocket, slowly handed it to Qi Xia, and said: "I know a lot of smart people, most of them have bad luck."

Qi Xia nodded and took the blindfold: "I can't refute this, after all, smart people rarely rely on luck when doing things."

"But we are gambling in the final analysis." The human pig said in a low voice, "The most important thing in gambling is "good luck", you are smart, but how about your luck?"

"I don't know." Qi Xia replied, "But we will know soon. "Qi Xia slowly put on the blindfold and put his hands on the table without moving.

The pig took the two bowls and began to shake the chess pieces.

This rule was originally designed to deal with some opportunists who would use white pieces as the base and then spread all the black pieces on the top to make it easier for them to touch.

But now, for Qi Xia's tactics, this rule has completely lost its effect.

The pig knew that no matter how he shook the chess pieces, the man in front of him would choose one without hesitation.

After all, he had done what he had to do, and next, he was ready to leave everything to his "luck".

Thinking of this, he shook it casually, and messed up the positions of the two bowls, and rearranged them one on the left and one on the right.

"Hey, which bowl do you want to choose?" The pig asked, "Your left hand... or your right hand?"

"I..." Qi Xia lowered his head and was silent for a while, then said, "Left, I choose left."

Lingo and Lao Lu were both startled, and they felt something was wrong.

Because Qi Xia's left hand was the bowl with ninety-nine chess pieces!

The pig's eyes suddenly lit up: "Very good, please choose a chess piece from it next."

He pushed the bowl in front of Qi Xia with a hint of sarcasm, as if he was laughing at him.

Qi Xia raised the corner of his mouth slightly and said, "Don't you want to test my luck? This bowl is just right for testing."

"What..." The pig was stunned, "You, you know that this bowl is "wrong"? !"

"Almost." Qi Xia slowly put his hand into the bowl and said, "In fact, choosing "left and right sides" is the same as choosing "rock, paper, scissors". It seems to be a balanced probability, but it is always biased due to human thinking. "

"What do you mean?" Lao Lu asked puzzledly.

"Just like most people will play scissors first when playing rock, paper, scissors, the probability is actually not balanced. "Qi Xia explained, "Paper will make your palm open and lose the sense of security, while Rock will clench your palm, making people feel subconsciously depressed, so Scissors becomes the most moderate choice. The same is true for choosing the left and right sides. People subconsciously think that "the left side is safer". After all, most people in the world are right-handed. They often use their right hands, and the probability of their right hands being injured is much higher than that of their left hands. So when choosing a safe direction, it is easy to choose "the left side". "

"You... are indeed not an ordinary person." said the pig man.

"There is no need to praise me, because you also understand these principles." Qi Xia said, "You put the ninety-nine chess pieces on my left hand side, it should not be accidental, right?"
