- Poisson[ <Mean> ]
- Returns a bar graph of a Poisson distribution with given mean λ.
- Poisson[ <Mean>, <Boolean Cumulative> ]
- Returns a bar graph of a Poisson distribution when Cumulative = false.
- Returns a graph of a cumulative Poisson distribution when Cumulative = true.
- The first parameter is same as above.
- Poisson[ <Mean>, <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 0.2 in the
Algebra View and \frac{4}{e³} in the 
CAS View.Poisson[3, 1, false]yields 0.15 in the Algebra View and \frac{3}{e³} in the CAS View.
