I really don't want to lie down and win

Xu Mang sighed,

Xiaoman, Xiaoman,

Why are you so young and cute?

"how?"

"Don't dare to accept the challenge?" Seeing Xu Mang's silence, Yang Xiaoman suddenly became interested, and immediately decided to give Xu Mang a little more discount.

"Ugh!"

"I will give you more strength. After we get married, you will have two days a week to play games all night." Yang Xiaoman said with a smile: "How is it? This condition is very attractive to you power?"

hiss!

OMG!

Is this going all out?

Xu Mang was taken aback. He decided to teach the cute and ignorant Xiaoman a lesson.

"Little Man..."

"Do you know why my grades in the first and second grades of high school are so poor?" Xu Mang asked solemnly.

"what?"

"Uh...Maybe it's lazy?" Yang Xiaoman said, "Maybe it's really stupid."

Xu Mang:

"Forget it, to tell you the truth, I read a book on behavioral psychology when I was in high school, and it changed my life a lot." Xu Mang said with a smile: "Most of the theory of cutting leeks is based on this book. here."

Yang Xiaoman looked confused, and asked curiously: "Is there any direct relationship between behavioral psychology and your desire to crack the code?"

"Just now I simulated the order of the password based on the force and wear characteristics on the password keys." Xu Mang said calmly: "I didn't mean that the password keys were weird before, two, seven, nine, zero, four The password keys are badly worn, so the password is the sequence of these four numbers."

"But it's useless to know, because there is only one chance, and I don't believe in probability very much, so I speculate based on the characteristics of force and wear." Xu Mang said: "Zero is the most severely worn out of the four buttons, the first password It's zero."

"The upper left edge of seven is worn, which is caused by the finger moving from right to left, so the second code seven, code nine is worn on the top, there is only one possibility, caused by the finger moving from top to bottom, so the third The password is two."

"The final password, zero seven two nine!" Xu Mang showed an extremely unbeatable smile: "My name is Xu Mang, and I am a master of behavioral psychology!"

words fell,

Under Yang Xiaoman's horrified expression, Xu Mang walked to the center of the crowd, knelt down, and silently pressed [-], the password sequence.

suddenly,

A click is heard.

So far,

The abandoned locker that had troubled everyone present for an entire hour was ruthlessly opened.

......

Chapter 292 From Logic to Mathematics (1/3)

This...

Is this serious?

Everyone present was deeply suspicious of this.

To put it bluntly, although this is just a password guessing game, most people regard it as a probability challenge.

of course,

The methods adopted by the people are not the same. Some people use probability limit theory, while some people use probability distribution, that is, the probability properties of random variables, and some people go too far and use Markov process to study the state of discrete event dynamic system space problem.

but,

The probability of all four-digit passwords appearing is equal to [-] times.

After that, everyone began to expand, because this is a four-digit password set artificially. From the perspective of human thinking, the probability of appearing a four-digit password is no longer equal, and the number of attempts will be greatly shortened.

Since then,

The small password cabinet has become a carnival for many mathematical geniuses and teachers, who are swaying their youth in probability theory.

result...

come out alone

He came up and ended the carnival of probability theory.

"..."

"..."

"..."

Is this a random event?

How else is it possible? !

Words,

Who is he?

at the same time,

The one who was the most angry was Yang Xiaoman, she felt that she had been tricked and cheated miserably by this guy.

Yang Xiaoman: #￣￣#

So angry!

I was actually cheated!

Let you pay a terrible price at night!

"Ugh?"

"You... You seem to be Xu Mang, right?" A certain student present recognized Xu Mang. He was a member of the representative team from Zhejiang Province. Complete failure... Xu Mang's face has been remembered ever since.

"..."
