1. The problem statement, all variables and given/known data If event A equals event B, then the probability of their intersection is 1. True or False? Apparently the correct answer is False. 3. The attempt at a solution If A=B then they should overlap entirely and their intersection should be 1? The only way I see this working is if A is a subset of B and therefore they do not overlap completely, but when the question states "equals" I would think this means they are the same.
