According to an airline, flights on a certain route are on time

7575%

of the time. Suppose

1717

flights are randomly selected and the number of on-time flights is recorded.

(a) Explain why this is a binomial experiment.

(b) Find and interpret the probability that exactly

1111

flights are on time.

1111

flights are on time.

(d) Find and interpret the probability that at least

1111

flights are on time.

(e) Find and interpret the probability that between

and

1111

flights, inclusive, are on time.
