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 97 flights are on time.
(b) at least 97 flights are on time.
(c) fewer than 106 flights are on time.
(d) between 106 and 113, inclusive are on time.
The required probabilities are as... View the full answer
