From Apache OpenOffice Wiki
Returns the smallest value for which the cumulative binomial distribution is greater than or equal to a criterion value.
CRITBINOM(n; p; a)
- With n independent trials, each with a probability p of success, CRITBINOM returns the number of successes, up to and including which are expected with a probability a. See the examples to relate this to BINOMDIST.
- CRITBINOM is useful in quality assurance procedures.
CRITBINOM(100; 0.5; 0.9)
- returns 56.
BINOMDIST(56; 100; 0.5; 1)
- returns approximately 0.9 (90%), the probability that heads will come up 56 or fewer times in 100 flips of a coin.
