The rates of on-time flights for commercial jets are
continuously tracked by the U.S. Department of Transportation.
Recently, Southwest Air had the best reate with 80 % of its flights
arriving on time. A test is conducted by randomly selecting 20
Southwest flights and observing whether they arrive on time.
(a) Find the probability that exactly 8 flights arrive on
time.
(b) Would it be unusual for Southwest to have 3 flights arrive
late? (Enter YES or NO)
