The table summarizes data on smoking status and perceived risk of smoking and is consistent with summary quantities obtained in a Gallup Poll conducted in November 2002. Assume that it is reasonable to consider these data as representative of the U.S. adult population.

Smoking Status	Very Harmful	Somewhat Harmful	Not Too Harmful	Not at All Harmful
Current Smoker	59	34	5	1
Former Smoker	80	18	3	2
Never Smoked	83	11	2	1

(c) What is the probability that a randomly selected U.S. adult views smoking as very harmful given that the selected individual is a current smoker? (Give the answer to four decimals places.)

(d) What is the probability that a randomly selected U.S. adult views smoking as very harmful given that the selected individual is a former smoker? (Give the answer to four decimals places.)
