Syntax

PROBBNML(p, n, m)

Arguments

p

is a numeric probability of success parameter.

Range 0 ≤ p ≤ 1
Data type DOUBLE

n

is an integer number of independent Bernoulli trials parameter.

Range n > 0
Data type INTEGER

m

is an integer number of successes random variable.

Range 0 ≤ m ≤ n
Data type INTEGER

Details

The PROBBNML function returns the probability that an observation from a binomial distribution, with probability of success p, number of trials n, and number of successes m, is less than or equal to m. To compute the probability that an observation is equal to a given value m, compute the difference of two probabilities from the binomial distribution for m and m−1 successes.
