2. Customers are used to evaluate preliminary product designs. In the past, 95% of highly successful products received good reviews, 60% of moderately successful products received good reviews, and 10% of poor products received good reviews. In addition, 40% of products have been highly successful, 35% have been moderately successful and 25% have been poor products. (a) What is the probability that a product attains a good review? (b) if a new design attains a good review, what is the probability that it will be a highly successful product?
