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)
