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.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
