how do i solve these

According to an airline, flights on a certain route are on time 80% 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) Find and interpret the probability that exactly 15 flights are on time. (c) Find and interpret the probability that fewer than 15 flights are on time. (d) Find and interpret the probability that at least 15 flights are on time. (e) Find and interpret the probability that between 13 and 15 flights, inclusive, are on time. (a) Identify the statements that explain why this is a binomial experiment. Select all that apply. LY A. The experiment is performed a fixed number of times. LY B. There are two mutually exclusive outcomes, success or failure. LY C. The probability of success is the same for each trial of the experiment. D. The experiment is performed until a desired number of successes is reached. E. There are three mutually exclusive possibly outcomes, arriving on-time, arriving early, and arriving late. F. Each trial depends on the previous trial. LY G. The trials are independent. (b) The probability that exactly 15 flights are on time is (Round to four decimal places as needed.)
