Step-by-step explanation:
Let E denotes the event that the first airline's flight is fully booked on a particular day, and F denotes the event that the second airline's flight is fully booked on that same day.
Given : P(E) = 0.7, P(F) = 0.6, and P(E ∩ F) = 0.49.
Then, by conditional probability formula , we have
Hence, the probability that the first airline's flight is fully booked given that the second airline's flight is fully booked.= 0.8167
