Consider 16 gallons of genetically modied tomatoes. Suppose that 75 % of those tomatoes have an increased resistance to pests, 50 % were engineered to have a longer shelf life, and 30 % have an increased resistance to pests and were engineered to have a longer shelf life. If one of these tomatoes is randomly selected, compute the probability that the tomato
(a) has an increased resistance to pests, but was not engineered to have a longer shelf life;
(b) has an increased resistance to pests or was engineered to have a longer shelf life;
(c) does not have an increased resistance to pests, but was engineered to have a longer shelf life;
(d) does not have an increased resistance to pests and was engineered to have a longer shelf life.
