Homework Equations
The Attempt at a Solution
so at first, i was totally lost. i did a google search, and found another physicsforums thread that went over this question. (https://www.physicsforums.com/showthread.php?t=174152). the solution for the most part made sense to me. however, I'm confused by the original hint, condition on whether or not the interchanged card is selected. what exactly does that mean? and is there another way to solve the problem, other than the solution on the other page?
