Tutor greenestamps has the right idea, but P(A2) should be P(A2 given A1) since the event A1 occurs first. And it will alter what happens with A2.


Similarly, P(A3) should be something along the lines of P(A3 given A1 and A2) or P(A3 given (A1 ∩ A2) ) to signal that events A1 and A2 occured before A3.
