binomial probability formula statistics. Binomial Probability Formula n Total number of trials x Total number of successful trials p probability of success in a single trial q probability of failure in a single trial 1-p. X total number of successes fail or pass tails or heads etc P probability of success on an individual experiment.
P is the probability of success on any given trial. P X 1 p n X where n n is the number of trials p p is the probability of success on a single trial and X X is the number of successes. N X.
Probabilities for a binomial random variable X can be found using the following formula for p x.
