A random variable X has a Bernoulli distribution with parameter p, where 0 ≤ p ≤ 1, if it has only two possible values, typically denoted 0 and 1. The probability mass function (pmf) of X is given by. p ( 0) = P ( X = 0) = 1 − p, p ( 1) = P ( X = 1) = p. The cumulative distribution function (cdf) of X is given by. granola cereal healthy benefits
