QUESTION: 33

The Theorem of Compound Probability states that for any two events A and B.

Solution:

**Correct Answer :- C**

**Explanation : **If two events, A and B, are mutually exclusive, then the probability that either A or B occurs is the sum of their probabilities.

For mutually inclusive events, P (A or B) = P(A) + P(B) - P(A and B).
