According to an airline, flights on a certain route are on time 8585% of the time. Suppose 1010 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 77 flights are on time. (c) Find and interpret the probability that fewer than 77 flights are on time. (d) Find and interpret the probability that at least 77 flights are on time. (e) Find and interpret the probability that between 55 and 77 flights, inclusive, are on time.
