- Arguments
- Takes the cumulative probability, the success probability, the number of successes and an optional output form.

Example
| Input | Result |
|---|---|
| invBinomN(0.01,0.7,49,1) | [[85,0.0104507566907][86,0.00709005432826]] |
Typing invBinomN(0.01,0.7,49,1) on the home screen and pressing ENTER returns [[85,0.0104507566907][86,0.00709005432826]].
