According to an airline, flights on a certain route are on time 75% of the time. Suppose 15 flights are randomly selected and the number of on-time flights is recorded. (a) Explain why this is a binomial experiment. (b) Find and interpret the probability that exactly 9 flights are on time. (c) Find and interpret the probability that fewer than 9 flights are on time. (d) Find and interpret the probability that at least 9 flights are on time. (e) Find and interpret the probability that between 7 and 9 flights, inclusive, are on time. . . . (a) Identify the statements that explain why this is a binomial experiment. Select all that apply. YA. The trials are independent. Y B. The probability of success is the same for each trial of the experiment.C. The experiment is performed until a desired number of successes is reached.D. Each trial depends on the previous trial. YE. There are two mutually exclusive outcomes, success or failure. LY F. The experiment is performed a fixed number of times.G. There are three mutually exclusive possibly outcomes, arriving on-time, arriving early, and arriving late. (b) The probability that exactly 9 flights are on time is (Round to four decimal places as needed.)
