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

80% of the time. Suppose 13 flights are randomly selected and the number of on-time flights is recorded.

(c) Find and interpret the probability that exactly

9 flights are on time.

(d) Find and interpret the probability that fewer than

9 flights are on time.

(e) Find and interpret the probability that at least

9 flights are on time.

(f) Find and interpret the probability that between

7 and 9 flights, inclusive, are on time.

I'm using a TI-84 calculator and do not know how to input the data to find fewer.
