One way to think of it is to realize that you are really dealing, not with 3 cards, but with 6 faces (3 red and 3 green). With a red face showing you know the card <b>CANNOT</b> be the green/green card -- thus 2 green faces are eliminated from possibility of being on other side -- what is left as possibilities are 2 "Shecky Riemann"https://www.blogger.com/profile/07065658607024191185noreply@blogger.com
