If it's truly random, so we're going to assume, we're going to assume that Bill's not cheating. So assume, assume truly random, truly random and that each of the sheets of paper have a one in four chance of being picked. What's the probability that Bill does not get picked? Well, there's, so let me, the probability that, I guess I'm gonna write this, Bill not picked on a night, on a night, well, there's four equally likely outcomes and three of them result in Bill not getting picked. So there's a 3 4th probability that Bill is not picked on a given night. Well, what's the probability that Bill's not picked three nights in a row? Let me write that down.
