Hypergeometric DistributionThe hypergeometric distribution is a discrete distribution and is used to describe the probability to find k observations of class 1 when n objects are drawn from a population of N objects, and the probability of a single element of class 1 equals p.
ExampleSuppose you have 20 balls in a bag, 8 blue ones, and 12 red ones. Now mix the balls in the bag and draw 15 balls. What is the probability to draw exactly 5 blue balls and 10 red balls? The answer to this question is given by the hypergeometric distribution function:
N = 20 |
