# BINOM.DIST

BINOM.DIST(number_s, trials, probability_s, cumulative)

Returns the probability distribution function OR the cumulative distribution function for a binomial distribution.

 number_s The number of successes out of the trials. trials The number of independent trials. probability_s The probability of a success on each trial. cumulative A logical value indicating the type of function to use:False = probability distribution function (equal to)True = cumulative probability function (equal to or less than)

 REMARKS
 * This function was added in Excel 2010 to replace the BINOMDIST function.* The binomial distribution is a discrete distribution* If "cumulative" = False / 0, then the height of the bell shaped curve at "x" is returned. This uses the probability mass function* If "cumulative" = True / 1, then the area under the curve to the left of "x" is returned. This uses the cumulative probability function* All the values are greater than zero.* You can use the BINOM.INV function to return the inverse of the probability distribution function for a binomial distribution.* For the Microsoft documentation refer to support.microsoft.com
