The number of strange things in a team of two people is 2, 3, 4, 5, 6, and the probability is 20%. Consider guessing the big picture.

Count two first.

The better chance of two brothers is 25%, the better chance of two scorpions is 25%, and the same chance of one of them is 50%.

Considering that the probability of meeting two monsters is 20%, do a multiplication of 20%*25%=5%.

The situation of three

12.5% probability 3 brothers 37.5%2 brothers 1 scorpion 37.5% 1 brother 2 scorpions 12.5%3 scorpions also have a big guess probability of 20%*50%= 10%.

Four situations

I won't write the specific calculation. The probability is 20%*5/ 16=6.25%.

Five cases are 10%

6 situation 5%

So the total probability is 5+10+6.25+10+5 = 36.25%.

Haha, so many people do business, and you often lose. Even if he calls for a five-combo, the chance of hitting a five-combo is almost impossible, and the chance of hitting an eight-combo is less than three ten thousandths.

How was the answer?
