According to an airline, flights on a certain route are on time 85% of the time. Suppose 10 flights are randomly selected and the number of on-time flights is recorded. (a) Explain why this is a binomial experiment. (b) Determine the values of n and p. (c) Find and interpret the probability that exactly 7 flights are on time. (d) Find and interpret the probability that fewer than 7 flights are on time. (e) Find and interpret the probability that at least 7 flights are on time. (f) Find and interpret the probability that between 5 and 7 flights, inclusive, are on time. (d) The probability that fewer than 7 flights are on time is (Round to four decimal places as needed.) Interpret the probability. In 100 trials of this experiment, it is expected that about will result in fewer than 7 flights being on time. (Round to the nearest whole number as needed.) (e) The probability that at least 7 flights are on time is (Round to four decimal places as needed.) Interpret the probability. In 100 trials of this experiment, it is expected that about will result in at least 7 flights being on time. (Round to the nearest whole number as needed.) (1) The probability that between 5 and 7 flights, inclusive, are on time is (Round to four decimal places as needed.)
