According to anairline, flights on a certain route are on time 90% of the time. Suppose 15 flights are randomly selected and the number of on time flights is recorded. Use technology to find the probabilities.
(a) Determine whether 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 at least 13 flights are on time.
(d) Find and interpret the probability that fewer than 13 flights are on time.
(e) Find and interpret the probability that between 11 and 13 flights, inclusive, are on time.
