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.
