p : F distribution probability
k Binomial Distribution
Binomial Probability
Command: BinomialPD䡺
Description: This command calculates the probability that a random variable that follows a
binomial distribution will be a given x value. For example, it determines the
probability of x successes when the probability of success p-trial is performed
n times.
