So inside the bigger circle, we have a smaller circle that has this guy right over here has an area of 16 pi. A point is selected at random from inside the larger circle. So we're going to randomly select some point in this larger circle. What is the probability that the point also lies in this smaller circle? So here's a little bit interesting because you actually have an infinite number of points in both of these circles. It's not kind of separate balls or marbles like we saw in the first example or separate numbers. There's actually an infinite number of points you can pick here.
