BINOM.DIST

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

Returns the probability of getting a specific number of successes using a binomial distribution.

number_s	The number of successes.
trials	The total number of trials.
probability_s	The probability of a success on each trial.
cumulative	A logical value indicating the type of function to use: False (or 0) = individual probability (equal to) True (<> 0) = cumulative probability (equal to or less than)

REMARKS

* For an illustrated example refer to the page under Distributions
* The binomial distribution is a discrete distribution
* The binomial distribution is used when there are only two possible outcomes.
* If any of the arguments are not numeric, then #VALUE! is returned.
* The "number_s" and "trials" are truncated to integers.
* If "number_s" < 0, then #NUM! is returned.
* If "number_s" > "trials", then #NUM! is returned.
* If "probability_s" < 0, then #NUM! is returned.
* If "probability_s" > 1, then #NUM! is returned.
* If "cumulative" = False, then the height of the curve at "x" is returned.
* If "cumulative" = True, then the area under the curve to the left of "x" is returned. Example 5.
* You can use the BINOM.INV function to return the number of trials needed for a specific amount of success 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.
* You can use the POISSON.DIST function return the probability distribution function OR the cumulative probability function for a poisson distribution.
* This function was added in Excel 2010 to replace the BINOMDIST function.
