Suppose that an electronics store runs a promotion. At the cash register, each separate item is independently given an instant discount. The discount amounts and chances are: Discount 25% off 10% off None Probability 0.05 0.35 0.60 This means two items might get the same discount or they could get different discounts. I wll purchase a camera priced at $200 and a video game priced at $80. Let X be the total amount saved in dollars at the cash register. It is possible that we wont save any money at all. What is the chance of this? P(X = 0 ). Express your answer as a proportion using 2 decimal places.
