As part of a promotional campaign, a supermarket is running a raffle for select customers. There are two boxes filled with raffle coupons. Each box contains red, blue, and yellow coupons. Each red coupon offers a $50 discount, each blue coupon offers a $100 discount, and each yellow coupon offers a $200 discount. Customers will draw one coupon from each box. What is the probability that a customer's discount coupons will be worth exactly $150? (Round to the nearest whole number.)

What's the probability of drawing a red/yellow/blue? 1/3?

cancer:

If so, then the only way to get $150 is either get a red then a blue or a blue then a red. The chances of either happening is 1/9 so add them together and you get 2/9 = .2222222222
