Trick
How to Win?
You have no skill at magic tricks, yet you make a bet with your friend for $25. You tell him to pick a card, take a look at it, and put it back in the deck. You then shuffle the deck as many times as your friend wishes. You will then hand back your friend's chosen card. Even though you possess no magic skill whatsoever, and you have no idea what your friend picked, you can still win this bet. How?
