Argument(s): INTEGERLIST

## Description

The density function for the hypergeometric distribution is given by:

where the three distribution parameters are:

- N is the total population
- m is the number of items in the selected population (e.g. the number of white balls in the full urn of N items)
- n is the size of the sample drawn (e.g. number of balls drawn)

In addition,

- x, the abscissa of the density function, indicates the number of successes (e.g. drawing a white ball)
