WebThe outcome of each trial can either be a success (p) or a failure (1 - p). Given below are the formulas for the probability distribution of a geometric distribution. Probability Distribution Function: F(x) = P (X ≤ x) = 1 - (1 - p) x; Probability Mass Function: P(X = x) = (1 - p) x - 1 p; Probability Distribution of a Binomial Distribution WebThe binomial distribution consists of the probabilities of each of the possible numbers of successes on N trials for independent events that each have a probability of π (the Greek letter pi) of occurring. For the coin flip example, N = 2 and π = 0.5. The formula for the binomial distribution is shown below:
