(a) Determine whether that is a binomian experiment.
(b) Find the probability that exactly 15 flights are on time.
(c) Find the probability that at least 15 flights are on time.
(d) Find the probability that fewer than 15 flights are on time.
(e) Find the probability that between 13 and 15 flights, inclusive, are on time.
