I'd estimate that the probability of having a two-person line is 16%, or 0.16. And it's important to realize that these are legitimate probabilities. Remember, to be a probability, it has to be between zero and one. It has to be zero and one. And if you look at all of the possible events, it should add up to one, because at least based on your observations, these are the possibilities. Obviously, in a real world, there might be some kind of crazy thing where more people go in line, but at least based on the events that you've seen, these three different events, and these are the only three that you've observed, based on your observations, these three should add, because these are the only three things you've observed, they should add up to one, and they do add up to one. Let's see, 36 plus 16 is 52.
