Against All Odds (Card Trick)
Imagine that you and a spectator do the impossible: Each of you has half a pack of cards and each of you randomly selects a card from your respective half which you exchange so that there is no funny business; you each turn over the card that the other gave you, and they both match: they are both RED ACES! What’s more, after each of you shuffles your own half, this is repeated, this time each of you have the two BLACK ACES, again, randomly selected and exchanged!
