Atravel agency books holiday tours to italy, greece, and other countries in europe. a supervisor notes that the probability that a client visits greece on a tour is 0.28, and the probability that a tour includes italy is 0.55. the probability that a client visits both greece and italy on the same tour is 0.11. what is the probability that a client chooses greece, or italy, or both countries, on a tour?

C)    0.72

Step-by-step explanation:

Let A represent the event that a client chooses to visit Italy on a tour. Let B represent the event that the client chooses to visit Greece. As a client may visit both countries on the same tour, the events A and B are not mutually exclusive.

P(A or B) = P(A) = P(B) - P(A and B) = 0.55 + 0.28 - 0.11 = 0.72

So the probability that a client chooses Greece, or Italy, or both countries, on a tour is 0.72.

the answer is (4,3)
