And so the oldest sibling right over here, he decides, well look, I'll just put all of our names into a bowl, and then I'll just randomly pick one of our names out of the bowl each night, and then that person is going to be, so this is the bowl right over here, and I'm just gonna put four sheets of paper in there, each of them's gonna have one of their names, and then he's just going to randomly pick it out each night and then that's the person who's going to do their dishes. So they all say, well, you know, that seems like a reasonably fair thing to do, and so they start that process. So let's say that after the first three nights, that he, the oldest brother here, and let's call him Bill, let's say after three nights, Bill has not had to do the dishes. So at that point, the rest of the siblings are starting to think maybe, just maybe something fishy is happening. So what I wanna think about is, what is the probability of that happening? What's the probability of three nights in a row, Bill does not get picked? If we assume that we were randomly taking, if Bill was truly randomly taking these things out of the bowl and not cheating in some way, what's the probability that that would happen, that three nights in a row, Bill would not be picked?
