A grocery store examines its shoppers' product selection and calculates the following: The probability that a randomly-chosen shopper buys apples is 0.21, that the shopper buys potato chips is 0.36, and that the shopper
buys both apples and potato chips is 0.09.

a) Let A = Randomly-chosen shopper buys apples, and C = Randomly-chosen shopper buys potato chips.
Sketch a Venn diagram or two-way table that summarizes the probabilities above.

b) Find each of the following
i. The probability that a randomly selected shopper buys apples or potato chips.
ii. The probability that a randomly-selected chopper buys potato chips or doesn’t buy apples.
iii. The probability that a randomly-selected shopper doesn’t buy apples and doesn’t buy potato chips.
