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.
