Chapter 85: why is it you again

Views:

"How is it possible that none of them are right? You must have deliberately said this in order to win the gambling game. That must be the case!" Yang Wei stared at Zu An fiercely, knowing that no matter how much he thought he could be right, all of them were all right. No, how is it possible.

"Yeah, how could Teacher Yang do all the wrong things."

"He's an arithmetic teacher, Zuan is too much."

"In order to win the gambling contract, deliberately lie, it is really despicable."

Hearing the whispers of the surrounding students, Zuan did not get angry. Instead, he took out the paper he had made and said: "Also, let you understand. Just look at the first question. The correct answer is 2. And 2, what you wrote is 10 and 15. It looks like a random guess, right?"

Yang Wei's old face became hot. He really guessed this question. Because the more he thought about it, the more confused he guessed the number. However, he refused to admit defeat and said: "You are deliberately making things difficult for this question. How can the messy conditions lead to this answer?"

"Really?" Zuan smiled contemptuously. "If you don't understand, I'll explain it to you..."

"A knows the sum of these two numbers, but doesn’t know what the two numbers are. If you give 3, don’t you know 1+2=3? Give you 40, you don’t know 20+20= 40? Don’t you know that 19+20=39? So there is a potential range. The “sum” should be between 4 and 38.

Then we start the reasoning from the situation where the sum is 4, 4=1+3=2+2, so A cannot judge that situation.

Let's look at B again. If the product of two numbers multiplied by B in his hand is 2, 3, 5, 7, 11, 13, 17, 19... and so on, he can immediately infer the two numbers. It is 1 and the product itself, because there is only one way to split. But he said that he didn't know, that proved that the number he held in his hand was not these.

Let's go back to A. Assuming that he has 4 in his hand, then according to B doesn't know to rule out the possibility of 1+3, then only 2 and 2 are left, which is eligible.

For any other number, there are several other possibilities. A can't judge the two numbers so quickly, and B can't judge it immediately afterwards. "

Zu'an couldn't help sighing: "Look, as long as the method is right, the first number is tried out. Isn't it easy? That's why I put it in the first question. How can I know that it is so simple? You don’t know how to do all the questions, hey~"

The people around suddenly whispered:

"Hey, what he said is quite simple."

"Cut, then why couldn't you do it just now."

"I just didn't expect it, you don't even think of Teacher Yang."

Hearing Zhou Jian's unteachable tone, Yang Wei's face flushed red: "Even if I made this question carelessly wrong, then for the next question, the probability of choosing which door is not all the same? , How could it be wrong!"

This was the first question he made, and it was also the most confident question.

People around them all agreed: "Yes, the probability of each door is not the same, shouldn't it matter if you change it or not?"

Yang Wei's words indeed represent the common sense cognition of ordinary people.

Zuan sighed: "It's just that their students made mistakes on this question. You, an arithmetic teacher, made the same mistake. It's really... hey..."

Seeing him hesitating to speak, but then aiming at himself, Yang Weifei almost exploded with anger: "Xio has succeeded in making his tongue, but what did you say is wrong?"

The anger from Yang Wei is +472!

Then Zuan said, "Is the chance of getting the treasure for the door you chose one-third? The probability of winning the prize for the remaining two doors is naturally two-thirds, and now I've eliminated them for you. A wrong choice, is the probability of the remaining door two-thirds? Of course you should change the door, so that the chance of winning is greater."

"Nonsense," said Yang Wei, "the probability of winning in each door is independent and should be one-third. How could it suddenly become two-thirds?"

Zuan shook his head: "It seems that it is really difficult to understand such a complicated concept based on your IQ. Let me explain it in another way. If there are 10,000 doors in front of you, and only one door has treasures, you can choose whatever you want. Is the probability of winning a lottery for a door only one in ten thousand? Does such a small probability mean that it is impossible to win a lottery? The treasures are all in the remaining doors, right? "

"At this time, I opened 9998 of the remaining 9999 doors. The back is empty. I will ask you the same question again. Don't you want to change it?"

"Of course I have to change." Yang Wei said subconsciously, but his face changed as soon as he spoke. Is it true that he is really wrong

"Your Excellency deserves to be an arithmetic teacher. You understand it so quickly that you can teach you." Zu An nodded with satisfaction.

Smoke is almost coming out of Yang Wei's head. On the surface, this guy is complimenting me, but why does it sound so harsh

The anger value from Yang Wei is +333!

Zuan went on to say: "Next is the question of pirates' elemental stones. The best allocation plan for pirate armor is (97, 0, 1, 2, 0) or (97, 0, 1, 0, 2), you see See your answer, right?"

Yang Wei jumped up immediately: "Nonsense, such a distribution plan is almost monopolized. How could other pirates agree to it?"

Zuan shook his head: "They have all said that these pirates are extremely smart people, and they can rationally analyze the pros and cons. It seems that you are going to make the allocation. Most of them are dead."

He didn’t sell off this time and then said: “We use the reverse method. First, we will discuss with Pirate No. 5 because he is the safest and there is no risk of being thrown into the sea. Therefore, his strategy is also the simplest, that is, it’s best to go ahead. All of the people at dies are gone, so he can have these 100 yuan stones alone.

Next, let’s look at No. 4. His chance of survival depends entirely on the existence of someone in front of him, because if all the pirates from No. 1 to No. 3 feed the sharks, then when only No. 4 and No. 5 remain, no matter what No. 4 proposes. Regardless of the distribution plan, No. 5 will definitely vote against it to allow No. 4 to feed the sharks so as to swallow all the raw stones. Even if No. 4 pleases No. 5 in order to save his life and proposes a plan of (0, 100) to allow No. 5 to monopolize the yuan, but No. 5 may still think that it is dangerous to keep No. 4 and vote against it to feed the sharks. Therefore, the rational No. 4 should not take such a risk and pin his hope of survival on the random selection of No. 5. Only by supporting No. 3 can he absolutely guarantee his own life.

Look at No. 3 again. After the above logical reasoning, he will propose a distribution plan like (100, 0, 0), because he knows that even if No. 4 gets nothing, he will still support him unconditionally and vote for it. Then Coupled with his 1 vote, he can securely win the 100 yuan stone.

However, No. 2 also knows the allocation plan of No. 3 through reasoning, so he will propose a plan of (98, 0, 1, 1). Because this plan is compared with the allocation plan of No. 3, No. 4 and No. 5 can get at least 1 yuan stone. The rational No. 4 and No. 5 will naturally think that this plan is more beneficial to them and support No. 2 and don’t want 2. The number is out and the number 3 is assigned. In this way, No. 2 can successfully take away 98 yuan stones.

Unfortunately, the No. 1 pirate is not a fuel-efficient lamp. After some reasoning, he also got an insight into the No. 2 distribution plan. The strategy he will adopt is to give up No. 2 and give 1 Yuan Shi to No. 3 and 2 Yuan Shi to No. 4 or No. 5 at the same time, that is, propose (97, 0, 1, 2, 0) or (97, 0, 1, 0, 2) distribution plan. Since the allocation plan of No. 1 is more profitable for No. 3 and No. 4 or No. 5 than the plan of No. 2, they will vote for No. 1, plus No. 1’s own vote. 97 yuan stones can easily fall into the No. 1 belt bag. "

The people around him breathed a sigh of relief: "These pirates are too clever, aren't they?"

"If there were such clever pirates in reality, it would be a terrible thing."

"Don't worry, this is just a hypothesis. How can such a powerful person in reality become a pirate."

"That's true."

At this time, Yang Wei had already lost his eyes, stupidly stuck there, and couldn't hear any sound.

Zu'an was a little dissatisfied at once, and was broken so soon, don't you want to contribute anger points to me? So he began to explain the correct answers to the following questions. As expected, none of Yang Wei's answers were correct during the whole process, but it was a pity that Yang Wei only contributed a few hundred points of anger, which was obviously completely broken.

"Oh my god, none of them are right. Teacher Yang is too bad, right?"

"Yes, he looks the best in his nostrils on weekdays, but he didn't expect his arithmetic skills to be so bad."

"Cut, it's not ashamed that such a person still comes to the college to be a teacher."

The gazes and cold words of the surrounding students pierced Yang Wei's heart like a knife. He roared and ran out of the classroom hurriedly, covering his ears. He didn't stop even if the people nearby called him. He just wanted to leave quickly. This place is too shameful. I thought I could easily trample on an ordinary student, but I didn't know it was trampled by the student. He knew that he had experienced this and he would never have the face to stay in the college anymore.

As a teacher, as a result, he couldn't even solve one of the questions asked by the students. I am afraid that he will not only become the laughingstock of Mingyue City, but also the laughingstock of all the surrounding counties and counties.

"Boss, you are too good!" Wei Suo ran over to give him a flattering shoulder, and the classmates also ran over to bring tea and water. The other party's arithmetic ability, even if the slightest level of cultivation is not possible, will have a future. The light is infinite, is it silly not to take advantage of this opportunity to indulge in it

Chu even Zhao originally wanted to run over to talk to his brother-in-law, but he didn't know that there were so many people around him that he couldn't squeeze it through, so he couldn't help but snorted: "A group of flatterers."

Ji Xiaoxi's small face flushed with excitement, but at the same time secretly worried for him, if this offends the college teacher, will there be any bad consequences

Pei Mianman showed a charming smile, which made the men next to her dizzy: "I had regretted doing a deal with this guy before, but now it seems that maybe I can really get something back from him."

Zheng Dan in the distance looked at the expressions of the women, and was secretly surprised. He thought that they were all rumors. Now it seems that Zuan and these women have a very close relationship. What kind of charm does this guy have? , Not only married Miss Chu, but also attracted these outstanding women

At this moment, there was a violent shout: "If you don't go to class, why are you all around here, want to rebel?"

Hearing this voice, many people shook their heads. Obviously, this voice had caused too much shadow on them. Wearing the striking Mediterranean hairstyle, holding a ruler in his hand, who is not the director of training Lu De

Seeing him coming, the people around him evaded a path automatically. He walked in and noticed that Zuan was sitting swaying and being pinched on his back by his classmates, and his brows subconsciously wrinkled.

However, seeing the graceful Shang Liuyu on the side, the frowning eyebrows stretched out instantly: "It turns out that Teacher Shang is also there. What happened here just now? I saw Yang Wei ran out with his face covered, how could I shout? He won't listen either."

"Maybe I feel a little embarrassed." Shang Liuyu smiled lightly, and roughly recounted what happened here. Her voice was soft and moving, even simply listening to her was a kind of ultimate enjoyment.

"Are you making trouble again?" Lu De's face was soft when he looked at Shang Liuyu, but his expression instantly became severe when he looked at Zuan.
