He described the game like this: using three colors of chess pieces, the chess pieces are divided into three colors, red, green and blue. There are six red ones and the green one is in the +L bag. Let's touch it. You can only touch 12 at a time. You can touch them all at once or touch them one by one. I made a special list. The possibilities are listed separately. 147568.336.345 and so on. The numbers above represent the arrangement of various colors: columns. Any chess piece of this color. One color three, one color five. How many colors are there, as long as the number of colors matches. It constitutes 345:

Except touching the 345 combination. Other combinations seem to give some returns. The boy didn't say clearly how to reward him. There are three kinds of chess pieces in the bag, red, green and blue. The quantity is 6/7/8 respectively. Each hand can catch 12 pieces, which means 3 pieces of one color, 4 pieces of one color and 5 pieces of another color. You can win money. Touch 345 and you will be fined 10. According to him, it seems so.

I happen to have a buddy who also plays this game, but the gameplay has changed a little.

But I have a friend who plays this kind of chess in the street. The reason is the same as the game this boy said. The game is like this: use 8 white flags and 8 black chess, put them in your pocket, and then draw a table. Let's touch it. Anyone who touches it has to pay a handling fee of 10 yuan. You can only touch five pieces at a time

Here 100. If all the 5s touched are white. Give 5 yuan if it's all white. Touch three is white, 5 yuan. Touch something else, even for nothing.

I talked to him once. This kind of game is completely unnecessary. I just killed you. You can win money without a thousand dollars? Yes, it seems that this unfortunate mathematician who doesn't know the invention of genius. This is a question of opportunity.

How is the probability of this game calculated? After all these years, I still remember:

The probability of 5 white is: 8/166/145/134/12 in ~ ~ a.

156/ 145/ 138/ 12 in ~ ~ B

The probability of 3 white is: 8/166/148/137/12 in ~ ~ C.

How much is it? Because I don't have a computer in my hand, I'll give you an answer if I do. Compare answers. I use letters instead. Convenient for the following answer.

If you touch 1000 times, I'll give you a formula and do it myself:

A times 100 plus b times 50 plus c times 5 ~ ~ = d.

Then multiply d by C~~~E ~ e ~ e.

E is the contact money 1000, and the person who sets up the game needs to pay the contact bonus.

And his actual income is 10 yuan times 1000. 1 1,000 yuan: Let's see if it is profiteering.

Can you understand this explanation?

And the one my friend said is a three-color game. If calculated by probability, it should be more complicated. I don't know how to forget it. That man with will can do it himself when he is idle and bored. Personally, I think. But the bureau is different. It all makes sense. I can kill you without a thousand dollars. So you'd better stay away from this situation in the street in the future, otherwise this thing will spend all the money in your pocket.

There is a saying: existence is the truth of existence. So don't be influenced by what you take for granted. Don't touch any scam in the street, just call it: No Jin Gangzuan. Dare not take porcelain work? Is that so? So whoever dares to put the bureau in front of the public in the street, you won't get the money. There are fools in this world. But it's definitely not a game set by these people. who the hell could that be ? guess
