The probability that a student passes the written test for a private pilot license is 0.75. Find the probability that the student
(a) Passes on the first attempt,
(b) Passes on the second attempt,
(c) Does not pass on the first or second attempt.
Find the indicated probabilities using the geometric distribution, the Poisson distribution, or the binomial distribution. Then determine whether the events are unusual. If convenient, use a table or technology to find the probabilities.
