The correct statement for two mutually exclusive events A and B is: (1) P(A) + P(B) = 1
This means that the sum of the probabilities of A and B is equal to 1
because if they are mutually exclusive, either A or B can occur, but not both.
Therefore, none of the options (1), (2), or (3) is correct.
The correct answer is (D) None of these.
