Acertain flight arrives on time 79 percent of the time. suppose 144 flights are randomly selected. use the normal approximation to the binomial to approximate the probability that

a) exactely 100 flights are on time

b) at least 100 flights are on time

c)fewer than 125 flights are on time

d) between 125 and 126, inclusive are on time

show step by step. especially if you used a calclator or table to find p after calculating the z score.
