HyperGeometric Command

HyperGeometric[ <Population Size>, <Number of Successes>, <Sample Size>]

Returns a bar graph of a Hypergeometric distribution.

Parameters:

Population size: number of balls in the urn

Number of Successes: number of white balls in the urn

Sample Size: number of balls drawn from the urn

The bar graph shows the probability function of the number of white balls in the sample.

HyperGeometric[ <Population Size>, <Number of Successes>, <Sample Size>, <Boolean Cumulative> ]

Returns a bar graph of a Hypergeometric distribution when Cumulative = false.

Returns a bar graph of a cumulative Hypergeometric distribution when Cumulative = true.

First two parameters are same as above.

HyperGeometric[ <Population Size>, <Number of Successes>, <Sample Size>, <Variable Value v>, <Boolean Cumulative> ]

Let X be a Binomial random variable.

Returns P( X = v) when Cumulative = false.

Returns P( X ≤ v) when Cumulative = true.

First two parameters are same as above.

CAS Specific Syntax

In CAS View only one syntax is allowed:

HyperGeometric[ <Population Size>, <Number of Successes>, <Sample Size>, <Variable Value v>, <Boolean Cumulative> ]

Let X be a Hypergeometric random variable.

Returns P( X = v) when Cumulative = false.

Returns P( X ≤ v) when Cumulative = true.

First three parameters are same as above.
