PROBBNML ( p , n , m )
p
is a numeric probability of success parameter.
RANGE: ‰ p ‰ 1
n
is an integer number of independent Bernoulli trials parameter.
RANGE: n > 0
m
is an integer number of successes random variable.
RANGE: ‰ m ‰ n
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.
