P (L ∩ O) = 0.23

Step-by-step explanation:

We are going to define the probabilistic events how:

E: Flights arrive early P (E) = 0.15

T: Flights arrive on time P (T) = 0.25

O: Flights are overbooked P (O) = 0.65

O: Flights are not overbooked

L: Flights arrive late

How 72 percent are late or not overbooked, then P (O ∪ L) = 0.72

Our question is : What is the probability that the flight selected will be late and not overbooked? It means, what is P (L ∩ O)

This probability may be calculated how:

P (L ∩ O) = P (L) + P (O) - P (O ∪ L)

1 = P (L) + P (E) + P (O)

1 = P (L) + 0.15 + 0.25

P (L) = 0.6

how P (0) = 0.65, then P (O) = 0.35

Thus

P (L ∩ O) = 0.6 + 0.35 - 0.72

P (L ∩ O) = 0.23
