Ethan wakes up one morning with a talking cat on his head. The cat refuses to budge until Ethan wins a game of probability. Without looking, Ethan must pick out a dime from his coin collection or two matching socks from his dresser, or do something else improbable. A very improbable story about a challenging math concept.
