Definition. This function returns the probabilities of a negative binomial distributed random variable. NEGBINOM.DIST() calculates the probability that there will be number_f failures before the last number_s when the constant probability of a success is probability_s.
Arguments
number_f (required). The number of failures
number_s (required). The number of successes
probability_s (required). The probability of a success
Note
Number_f and number_s are truncated to integers. If one of the arguments isn’t a numeric expression, the NEGBINOM.DIST() function returns the #VALUE! error.
If probability_s is less than 0 or greater than 1, the NEGBINOM.DIST() function returns the ...
