HyperGeometric distribution

HyperGeometric(Trials,PosEvents,Size)

The hypergeometric distribution describes the number of times an event occurs in a fixed number of trials without replacement -- e.g., the number of red balls in a sample of Trials balls drawn without replacement from an urn containing Size balls of which PosEvents are red. Thus, the parameters are: Trials: The sample size -— e.g., the number of balls drawn from an urn without replacement. Cannot be larger than Size. PosEvents: The total number of successful events in the population -- e.g, the number of red balls in the urn. Size: The population size -- e.g., the total number of balls in the urn, red and non-red.
