An airline gathers data on late departures and early arrivals over a month. it finds that the probability of a late
departure is 12 percent, the probability of an early arrival is 27 percent, and the probability of both a late departure
and an early arrival is 4 percent. which equation shows how to correctly calculate the probability of a late departure
or an early arrival?
p(late departure or early arrival) = 0.12 + 0.04
plate departure or early arrival) = 0.12 +0.27
p(late departure or early arrival) = 0.12 +0.27 - 0.04
sllate departure or early arrival) = 0.27 +0.04 - 0.12
