Okay, consider this puzzle. You have a pack of 52 shuffled cards. You divide them into two stacks of 26 cards.
What is the probability that the number of red cards in one stack equals the number of black cards in the other stack?

1.0 if it was a brand new pack of cards.

Mort thinks he's tricky. But I've heard that one before.

Take a deck of 52 cards. Shuffle them. Draw the cards 2 at a time. If the cards are different colors, discard them. If they are both red, put them in one pile. If they are both black, put them in a second pile. Count the red and black piles.
