Question

If A and B are mutually exclusive, and if P(A) = 23% and P(B) = 16%, what is P(A or B)?

P(A or B)=[%

Answer 1

P(A or B) = 39%

Explanation:

If A and B are mutually exclusive, they cannot occur at the same time, therefore their probabilities are added. This means P(A or B) = P(A) + P(B) = 23% + 16% = 39%
