66

flights are on time.

(d) Find and interpret the probability that fewer than

66

flights are on time.

(e) Find and interpret the probability that between

55

and

77

flights, inclusive, are on time.

Answer #1

According to an airline, the probability of flights on a certain route are on time is 0.85 .

Suppose 88 flights are randomly selected and recorded .

**(a) Yes , it is definitely follow Binomial distribution
with parameters n=88 and p=0.85 .**

**(b) probability that exactly 66 flights are on time =
0.0049**

**(c) probability that at least 66 flights are on time =
0.9953**

**(d) probability that fewer than 66 flights are on time.=
0.0046**

**(e) probability that between 55 and 77 =
0.7863**
