According to an airline, flights on a certain route are on time 80% of the time. Suppose 20 flights are randomly se (a) Explain why this is a binomial experiment. (b) Determine the values of n and p. (c) Find the probability that exactly 12 flights are on time. (d) Find the probability that fewer than 12 flights are on time. (e) Find the probability that at least 12 flights are on time. () Find the probability that between 10 and 12 flights, inclusive, are on time. .. (c) The probability that exactly 12 flights are on time is 0.0222 (Round to four decimal places as needed.) (d) The probability that fewer than 12 flights are on time is 0.0125 (Round to four decimal places as needed.) (e) The probability that at least 12 flights are on time is 0.9875 (Round to four decimal places as needed.) (f) The probability that between 10 and 12 flights, inclusive, are on time is (Round to four decimal places as needed.)
