A certain flight arrives on time 89 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 110 flights are on time. (d) between 110 and 113, inclusive are on time.
