单词	hypergeometric distribution
释义	hypergeometric distribution Suppose that, in a set of N items, M items have a certain property and the remainder do not. A sample of n items is taken from the set. The discrete probability distribution for the number r of items in the sample having the property has probability mass function given by where r runs from 0 up to the smaller of M and n. This is called a hypergeometric distribution. The mean is , and the variance is
