Question
A and B are mutually exclusive events. P(A) = 0.60 and P(B) = 0.30. What is P(A or B)?A.0.90B.0.15C.0.18D.0.72
Solution
The probability of either event A or event B occurring is given by the sum of their individual probabilities. This is because A and B are mutually exclusive events, meaning they cannot both occur at the same time.
So, P(A or B) = P(A) + P(B)
Substituting the given values:
P(A or B) = 0.60 + 0.30 = 0.90
So, the answer is A. 0.90.
