Question

If events A and B are mutually exclusive, then P(A or B) = P(A) + P(B).

Question 5 options:
True
False

Answer 1

True.

If events A and B are mutually exclusive, it means that they cannot occur at the same time. Therefore, the probability of either event A or event B occurring is simply the sum of their individual probabilities. This can be expressed as:

P(A or B) = P(A) + P(B)

So the statement is true.
