When beginning any approximation problem, ask yourself, "What do I need to know in order to solve this?" This particular problem asks about Americans, so the total number A of Americans is a good place to start. In actuality, there are a little over 325 million. Choose a convenient approximation for this value, express it using scientific notation, and enter it below. Do not check your answer yet.

Customers are used to evaluate preliminary product designs. in the past, 93% of highly successful products received good reviews, 51% of moderately successful products received good reviews, and 14% 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. round your answers to four decimal places (e. g. 98.) 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? (c) if a product does not attain a good review, what is the probability that it will be a highly successful product?
