I'm playing hide and seek around the world

Su Ya took her hand out of his palm, blushing and began to shuffle the cards.

She was very careful, for fear of making too much trouble.

After simply shuffling twice, she spread out the cards on the table.

The two searched one by one from the beginning to the end, and it turned out that there was an ace of hearts and a 4 of diamonds next to each other.

Su Mu stared at Su Ya closely.

Sure enough, she caught a look of relief in her eyes.

"Hey, fate says we should be together."

"Hmph, I don't believe it." With a smile in her eyes, Su Ya didn't believe his nonsense at all.

Looking at Su Mu with a smirk on her face, she frowned slightly.

"Is this a magic trick? Have you tampered with the playing cards?"

Su Ya picked up the playing cards and checked them one by one, carefully looking at the front and back as well as the patterns on the cards several times.

There was a thin layer of mist in her eyes, thinking about why.

Su Mu looked at her with a smile, "I didn't cheat, and I didn't do any tricks. If I want to say anything, it's probably God's will."

Yuelao's hemp rope was tightly tied.

Besides

In fact, no matter any two numbers, there is actually about 80% probability that they will be next to each other.

This is mathematics, not divination.

If the 20% really appeared, Su Mu would say, "I think we must have not paid enough attention just now."

Su Ya stared sideways at the poker cards on the table, it must not be that simple.

But Su Mu said that he didn't cheat, why?

After two seconds, Su Ya finally figured it out, "I understand, this is a matter of probability."

In fact, Su Mu really didn't cheat. This is a typical probability question.

There are 4 1s in the deck, assuming there are 1 positions next to each 2.

Then there are 8 positions.

Draw 48 times from the remaining 8 cards and fill in these 8 positions, as long as one of them is 4.

Then 48 of these 4 are all 4.

Then the probability at this time is

4/48 times 8

That is 32/48=0.6666

About 67% probability.

But this is only a theoretical calculation value. In fact, if you want to calculate it accurately, you need to use the following method:

Every time a position is filled, a card is consumed, so——

If the calculation is not replaced, it should be the case where 8 is not drawn after subtracting 4 times with the full probability:

First, we need to know the probability that each of the 4 1s has 2 vacancies:

1 cannot be at the head and tail, and each side cannot be 1, and there are at least two spaces between each other. This probability is:

（1-（2*4/52））*（（1-（48/51）*（47/50））+（1-（48/50）*（47/49））+（1-（48/49）*（47/48）））=0.19

The probability of not drawing 8 4 times is:

0.19*（44/48）*（43/47）*（42/46）*（41/45）*(40/44)*(39/43)*(38/42)*(37/41)

=0.19*0.91*0.91*0.91*0.91*0.91*0.9*0.9*0.9

= 0.08

Then calculate 7 positions, that is, among the 4 1s, two 1s are next to each other, or one 1 is at the top or bottom of the pile, resulting in a situation where the number of positions is reduced by 1.

(N steps are omitted in the steps, don't hit the children, this chapter is really dry, I didn't count the number of words here when I wrote it.)

Until the most extreme four 4s are close together, and when they are at the beginning and end, there is only one position:

The probability is:

2*（4/52）*（3/51）*（2/50）*（1/49）*（4/48）

=2*0.07*0.05*0.04*0.02*0.08

= 0.000000000448

This probability is 1 minus other impossible probability cases.

也就是1-0.08-0.11-0.01-0001……

最后的结果，差不多0.8，也就是说80%的概率会有1个4出现在1个1的旁边。

……

"You scoundrel, aren't you afraid of a small probability event?" Su Ya looked at him sullenly.

"Not afraid." Su Mu smiled, "Because I'm with my sister."

It was ordained.

"Yuelao's hemp rope almost strangled me to death."

Su Ya's ears turned red quickly, and the mist in her eyes tended to get worse.

"Where did you learn this? Why did you suddenly become a different person after you came back?"

"Uh.....it's the romance of mathematics."

"No, that's not right." Su Ya got up suspiciously, walked to Su Mu's side and looked carefully, "Did you learn this on your phone to deal with me?"

"Hmph, don't watch small movies now, are you learning to be a scumbag?"

Su Mu: "???"

A facial cleanser operation.

.......

Three days later!

Su Muhua, who was ready to go at home, entered the hide-and-seek space for a ray of white light!
