Suppose I find a barrel, sealed at the top, but with a hole large enough for a hand. I reach in and feel a small, curved object. I pull the object out, and it’s blue—a bluish egg. Next I reach in and feel something hard and flat, with edges—which, when I extract it, proves to be a red cube. I pull out 11 eggs and 8 cubes, and every egg is blue, and every cube is red. Now I reach in and I feel another egg-shaped object. Before I pull it out and look, I have to guess: What will it look like?
