Poisson Command
From GeoGebra Manual
- Poisson[ <Mean λ> ]
- Returns a bar graph of a Poisson distribution with given mean λ.
- Poisson[ <Mean λ>, <Boolean Cumulative> ]
- Returns a bar graph of a Poisson distribution when Cumulative = false.
- Returns a bar graph of a cumulative Poisson distribution when Cumulative = true.
- The first parameter is same as above.
- Poisson[ <Mean λ>, <Variable Value v>, <Boolean Cumulative> ]
- Let X be a Poisson random variable.
- Returns P( X = v) when Cumulative = false.
- Returns P( X ≤ v) when Cumulative = true.
- First parameter is same as above.
CAS Syntax
- Poisson[ <Mean λ>, <Variable Value v>, <Boolean Cumulative> ]
- Let X be a Poisson random variable.
- Returns P( X = v) when Cumulative = false.
- Returns P( X ≤ v) when Cumulative = true.
- First parameter is same as above.
- Examples:
Poisson[3, 1, true]yields \frac{4}{e³}.Poisson[3, 1, false]yields \frac{3}{e³}.
