A certain flight arrives on time 89 percent of the time. Suppose 119 flights are randomly selected. Use the normal approximation to the binomial to approximate the probability that
​(a) exactly 113 flights are on time.
​(b) at least 113 flights are on time.
​(c) fewer than 107 flights are on time.
​(d) between 107 and 114​, inclusive are on time.
