- Pascal[ <Number of Successes r>, <Probability of Success p> ]
- Returns a bar graph of a Pascal distribution.
- 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.
