Unformatted text preview: repetitions (independent) of a Bernoulli trial. Then (a) X is a binomial random variable. (b) X is a geometric random variable. (c) X ± 1 is a binomial random variable. (d) X is a Bernoulli random variable. Problem 5 If X is a geometric random variable with parameter p (i.e., the probability of success of the associated Bernoulli trial is p ), then (a) P ( X = 1) = (1 ± p ) p . (b) P ( X = 1) = p . (c) P ( X = 1) = p 2 . (d) P ( X = 1) = 1 ± p ....
