CRITBINOM

Returns the smallest value for which the cumulative binomial distribution is greater than or equal to a criterion value.

Syntax:

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.

Example:

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.
