Answer:
The probability of exercise in cruise ships = 73
Step-by-step explanation:
Let A be the probability of rock climbing
Let B be the probability of ice skating
Let C be the probability of fitness center
P(A) = 36, P(B) = 44, P(C) = 27
P(A ∩ B) = 14, P(A ∩ C) = 11, P(B ∩ C) = 9
P(A ∩ B ∩ C)=0
By formula,
P(A ∪ B ∪ C) = P(A) + P(B) + P(C) − P(A ∩ B) − P(A ∩ C) − P(B ∩ C) + P(A ∩ B ∩ C).
Substituting the values in the above formula,
P(A ∪ B ∪ C) = 36 + 44 + 27 - 14 - 11 - 9 + 0
= 107 - 14 - 11 - 9
P(A ∪ B ∪ C) = 73
