All Life's a Game (Show)


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:

Prize

Chances

Washer-dryer

5%

Toaster Oven

10%

Tropical Getaway

1%

Pet Rocks

84%

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

What are your chances of winning a household appliance? (in other words, the washer-dryer OR the toaster oven?)

I think I have the answer: 5% + 10% = 15%
