There's actually an infinite number of points you can pick here. So when we talk about the probability that the point also lies in the smaller circle, we're really thinking about the percentage of the points in the larger circle that are also in the smaller circle. Or another way to think about it is the probability that if we were to pick a point from this larger circle, the probability that it's also in the smaller circle is really just going to be the percentage of the larger circle that is the smaller circle. I know that might sound confusing, but we really just have to figure out the areas for both of them. It's really just going to be the ratios. So let's think about that. So there's a temptation to just use this 36 pi up here.
