Explanation / Answer

(a) Count of non-delay departures= 363

Probability that a flight will depart early or on-time = 363/500 = 0.726

(b) Count of late arrival = 170

Calculate the probability that a flight will arrive late = 170/500 = 0.34

(c) Count of late departure = 137; Probability = 137/500 = 0.274

Count of early arrival = 330; Probability = 330/500 = 0.66

Calculate the probability that a flight departs late or arrives early = 0.274 + 0.66 = 0.934
