Pascal Command

Pascal[ <Number of Successes r>, <Probability of Success p> ]

Returns a bar graph of a Pascal distribution. Each bar in the bar

graph shows probability of having given number of failures before r successes.

Parameters:

Number of Succeses: number of independent Bernoulli trials that must be successful

Probability of Success: probability of success in one trial

Pascal[ <Number of Successes>, <Probability of Success>, <Boolean Cumulative> ]

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

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

First two parameters are same as above.

Pascal[ <Number of Successes>, <Probability of Success>, <Variable Value v>, <Boolean Cumulative> ]

Let X be a Pascal 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:

Pascal[ <Number of Successes>, <Probability of Success>, <Variable Value v>, <Boolean Cumulative> ]

Let X be a Pascal random variable.

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

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