A certain flight arrives on time 80 percent of the time. Suppose 121 flights are randomly selected. Use the normal approximation to the binomial to approximate the probability that (a) exactly 103 flights are on time. (b) at least 103 flights are on time. (c) fewer than 88 flights are on time. (d) between 88 and 92, inclusive are on time. (a) P(103) (Round to four decimal places as needed.)
