Timothy and Urban play a game with two dice. But they do not use the numbers. Some of the faces are painted red and the others blue. Each player throws the dice in turn. Timothy wins when the two top faces are the same color. Urban wins when the colors are different. Their chances are even.
The first die has 5 red faces and 1 blue face. How many red and how many blue are there on the second die?
It didn't make any difference what the make-up of the first die is. The half-and-half nature of the second die (3 red, 3 blue) assures that whatever the first die shows, there's a 50% chance of a match on the second.
