- E(X) = p V(X) = p(1 p): The Binomial Distribution. Binomial Experiments Consider the following type of random experiment: 1 The experiment consists of n repeated Bernoulli trials - each trial has only two possible outcomes labelled assuccessand failure; 2 The trials areindependent- the outcome of any trial has no e ect on the probability of the others; 3 The probability of success in each
