Web19 mrt. 2015 · There are plenty of events with probability 0 that are not the empty set. So the argument for the case Pr ( A) = 0 has to be modified. Here is how to do it. Because A ∩ B ⊆ A, we have Pr ( A ∩ B) ≤ Pr ( A). It follows that Pr ( A ∩ B) = 0. For the Pr ( A) = 1 case, you also need to modify the argument.
