1) If events A and B are independent, then P (A & B) = P(A)P(B) Mr F says: True by definition, as your textbook and/or notes would surely say.
2) It is possible for two independent events with positive probabilities to be mutually exclusive Mr F says: False. By definition, Pr(A & B) = 0 if A and B are mutually exclusive events. But if A and B are independent events with positive probabilities, Pr(A & B) = Pr(A) Pr(B) neq 0 ....
