Question 17, Mathematical Physics of Guangdong Paper in 2009 College Entrance Examination (3) Why can't it be done with hypergeometric distribution?
Yes ~ but the standard answer is binomial distribution. It is said that some teachers will not correct papers so carefully in order to achieve the required speed. If they see that your answer is wrong, they may kill Didi directly, so the college entrance examination has a certain component of trampling on shit.

Binomial distribution solution

The probability of 1 white ball is 7 * (219/365) * (146/365) 6.

The probability of white ball 0 is (146/365) 7.

So the probability of at least two white balls is1-7 * (219/365) * (146/365) 6-(146/365) 7.
