Unformatted text preview: Interpret the situation as a binomial experiment. Identify the trials. Atrial is selecting an email password of a user over age 40.
Identify a success. Atrial is a success if the password contains the user‘s actual name. It is a failure if the
password does not contain the user's actual name. Find the probability. The question describes a binomial experiment in which the number of trials is 4, the
probability of success is 0.84, and the probability;r of failure is 1 — 0.84 = 0.15. Find the
probability of exactly 1 successes using a binomial distribution with n = 4, p = 0.34, and or =
0.15. m1) = nclp lqn_ 1 .c1 - 0341-0154“
