WebObjectives. Upon completion of this lesson, you should be able to: To understand the derivation of the formula for the binomial probability mass function. To verify that the binomial p.m.f. is a valid p.m.f. To learn the necessary conditions for which a discrete random variable X is a binomial random variable. WebDefinition 3.3. 1. 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.
