Your three cabinets illustrates the same principle as the puzzle I use to illustrate why I hate statisitcs: 1. A family has two children; the older one is a boy. What is the probability that both children are boys? 2. A family has two children; at least one of them is a boy. What is the probability that both children are boys? The official answers to those two questions differ. My theory is that if something so simple defies my intuition, I had better stick to empirical measurements of stochastic processes, because there is no way I am going to analyze a real-world problem accurately... =Ned=
