Customers are used to evaluate preliminary product designs. In the past, 95% of highly successful products received good reviews, 40% 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 20% have been poor products. What is the probability that a product attains a good review? If a new design attains a good review, what is the probability that it will be a highly successful product? a. NONE b. 0.540, 0.704 O. 0.460, 0.620 Od.0.585, 0.615
