What are the odds? Ethan wakes up one morning to find a very strange cat stuck on his head. The cat, Odds, 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. If he doesn't, Odds is there to stay, and Ethan has a 100% chance of missing his big soccer game. A very improbable story about a challenging math concept.
