According to an airline, flights on a certain route are on time 75% of the time. Suppose 20 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 13 flights are on time. (c) Find and interpret the probability that fewer than 13 flights are on time. (d) Find and interpret the probability that at least 13 flights are on time. (e) Find and interpret the probability that between 11 and 13 flights, inclusive, are on time. (a) Identify the statements that explain why this is a binomial experiment. Select all that apply. O A. There are two mutually exclusive outcomes, success or failure. B. There are three mutually exclusive possibly outcomes, arriving on-time, arriving early, and arriving late. C. The probability of success is the same for each trial of the experiment. O D. The experiment is performed a fixed number of times. O E. Each trial depends on the previous trial. F. The trials are independent. OG. The experiment is performed until a desired number of successes is reached. @ OO0 O O O D
