When I meet a friend playing SimCity on Tuesday, I have a 62% chance of buying the game. When I meet another friend playing SimCity on Wednesday, I have a 84% chance of buying the game.
I need to find the total probability that I buy Simcity.
But when I add 62% to 84% that makes 146% which I am pretty sure is wrong. So how do I find the total probability in this case?
