And let's say in theory you're flipping a completely fair coin and you're flipping it in a way that is completely fair. Well, there you know you have two outcomes. The coin will either result, either heads will be on top or head tails will be on top. And so theoretically you say, well look, if I want to figure out the probability of getting a heads, in theory I have two equally likely possibilities and heads is one of those two equally likely possibilities. So you have a 1 1⁄2 probability. And once again, if in theory the coin is definitely fair, it's a fair coin and it's flipped in a very fair way, then this is true. You have a 1 1⁄2 probability.
