A company launches an advertising campaign of its new product on TV, radio and in print media in an area where 30% watch TV, 50% listen to the radio and the rest rely on newspapers for all information. It is estimated that a person who sees the advertisement on TV will buy the product with probability 0:6. A person who has heard it on radio is expected to buy the product with probability 0:3 and seeing the advertisement in print will convince a person to buy the product with probability 0:1. A consumer, chosen at random, is found to have purchased the product. What is the probability she heard about the product on radio ?
