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? I encourage you to pause the video and think about that. Well, let's think about the probability that Bill's not picked on a given night. If it's truly random, so we're going to assume, we're going to assume that Bill's not cheating.
