Impossible Card Magic Trick Math Question
Posted on 2005-04-10
Don't think this question has a solution but was asked this:
With two decks of cards, one with red and one with orange backs. Audience picks five cards. The Magician's Helper shows both sides of four of the five cards in some order to the Magician. The Magician needs to determine the value, suit and back color of the fifth card. How would you go about doing this using Counting/Pigeonhole methods?
