A certain flight arrives on time 89 percent of the time. Suppose 144 flights are randomly selected. Use the normal approximation to the binomial to approximate the probability that (a) exactly 120 flights are on time. (b) at least 120 flights are on time. (c) fewer than 136 flights are on time. (d) between 136 and 138, inclusive are on time. (a) P(120) = (Round to four decimal places as needed.)
