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) = [[probability distribution function]] (equal to) True (<> 0) = [[cumulative probability function]] (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. * For the Microsoft documentation refer to support.microsoft.com |
