There's one of two values for a sample I can get. And right here, the values I said, you're either voting for candidate A or you're voting for candidate B. It's very hard to deal with those values. You can't calculate a mean between A and B and all of that. Those are letters. They're not numbers. So to make it manipulatable mathematically, we're going to say sampling someone who's going to vote for A is equivalent to sampling a 0.
