,
mean
,
cumulative
)

- mean: The mean of the distribution.
- cumulative: The type of distribution to use. FALSE = probability mass function; TRUE = cumulative distribution function.
Example
Formula | Result |
|---|---|
=POISSON(15,25,TRUE) | 0.022293 |
=POISSON(15,25,FALSE) | 0.009891 |
Notes
- This function does the same action as POISSON.DIST().
- Worksheets supports only integer values ofx.
