Assume that a marketing study showed that on a winter Friday evening at 8 P.M., 10% of adult women watch a program on network A, 8% watch a competing program on network C, and 14% watch a third program on network N. Assume that switching between programs does not occur. Chips ‘n' Fish Restaurants advertise on all three networks during this time period. However, studies show that only 70% of viewers of networks A and C and 60% of the viewers of network N actually pay close enough attention to the ad to remember it the next day. If an adult woman is interviewed on
Saturday,
(a) what is the probability that she will remember seeing the ad?
(b) If an adultwoman remembers seeing the ad, what is the probability that she watched the program on network C?
