Definition of hypergeometric distribution
: a probability function f(x) that gives the probability of obtaining exactly x elements of one kind and n - x elements of another if n elements are chosen at random without replacement from a finite population containing N elements of which M are of the first kind and N - M are of the second kind and that has the form {latex}f(x) = \frac{\binom{M}{x} \binom{N - M}{n - x}}{\binom{N}{n}}\text{where} \binom{M}{x} = \frac{M!}{x! (M - x)!}{/latex}
