BINOM.INV

BINOM.INV(trials, probability_s, alpha)

Returns the number of trials needed for a specific amount of success using a binomial distribution.

trialsThe total number of trials.
probability_sThe probability of a success on each trial.
alphaThe cumulative probability you want to find.

REMARKS
* For an illustrated example refer to the page under [[Distributions]]
* The binomial distribution is a [[discrete distribution]]
* This function will return the smallest number of trials needed for which the cumulative distribution is greater than or equal to "alpha".
* If any of the arguments are not numeric, then #VALUE! is returned.
* If "trials" is not an integer, it will be truncated.
* If "trials" < 0, then #NUM! is returned.
* If "probability_s" < 0, then #NUM! is returned.
* If "probability_s" > 1, then #NUM! is returned.
* If "alpha" < 0, then #NUM! is returned.
* If "alpha" > 1, then #MUM! is returned.
* You can use the BINOM.DIST function to return the probability of getting a specific number of successes using a binomial distribution.
* You can use the BINOM.DIST.RANGE function to return the probability of a trial result using a binomial distribution.
* You can use the NEGBINOM.DIST function to return the probability distribution function OR the cumulative probability function for a negative binomial distribution.
* This function was added in Excel 2010 to replace the CRITBINOM function.
