A certain flight arrives on time 86 percent of the time. Suppose 187 flights are randomly selected. Use the normal approximation to the binomial to approximate the probability that (a) exactly 148 flights are on time. (b) at least 148 flights are on time. (c) fewer than 173 flights are on time. (d) between 173 and 174, inclusive are on time. (a) P(148)equals 4.745 (Round to four decimal places as needed.)
