According to an airline, flights on a certain route are on time
85% of the time. Suppose 25 flights are randomly selected and the number of on-time flights is recorded.
(a) Explain why this is a binomial experiment.
(b) Determine the values of n and p.
(c) Find and interpret the probability that exactly 18 flights are on time.
(d) Find and interpret the probability that fewer than 18
flights are on time.
(e) Find and interpret the probability that at least 18
flights are on time.
(f) Find and interpret the probability that between 16 and 18
flights, inclusive, are on time.
