Question:

Environmental engineers classify U.S. consumers into five groups based on consumers’ feelings about environmentalism:
1. Basic browns claim they don’t have the knowledge to understand environmental problems.
2. True-blue greens use biodegradable products.
3. Greenback greens support requiring new cars to run on alternative fuel.
4. Sprouts recycle newspapers regularly. 5. Grousers believe industries, not individuals, should solve environmental problems. Assume the proportion of consumers in each group is shown in the table below. Suppose a U.S. consumer is selected at random and his (her) feelings about environmentalism determined.

a. List the simple events for the experiment.
b. Assign reasonable probabilities to the simple events.
c. Find the probability that the consumer is either a basic brown or a grouser.
d. Find the probability that the consumer supports environmentalism in some fashion (i.e., the consumer is a true-blue green, a greenback green, or a sprout).
