2: All Life’s a Game

Let’s say you are on a game show, with several fab-u-lous prizes: a 5-speed
automatic washer-dryer, a deluxe self-cleaning toaster-oven,
a one-week all-expenses-paid Tropical Getaway, or the consolation prize of
2 dozen pet rocks. Your chances are as follows:

Furthermore, the rules of the game show state that you will win one and only

What are your chances of winning a household appliance? (in other words,
