The hypergeometric distribution gives the probability of drawing a number of a type of elements from a dichotomous distribution, when we extract the elements at the same time or without devolution. For example, we use the hypergeometric distribution to calculate the probability of drawing 10 white balls when we extract 20 balls from an urn with 40 white and 60 balck balls.
