Q1- Customers are used to evaluate preliminary product design. 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, 45% of products have been highly successful, 30% 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 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?

29% of college students say they use credit cards because of the rewards program. You randomly select 10 college students and ask each to name the reason he or she uses credit cards. Find the probability that the number of college students who say they use credit cards because of the rewards program is (a) exactly two, (b) more than two, and (c) between two and five inclusive. If convenient, use technology to find the probabilities. (a) P(2)=(Round to the nearest thousandth as needed.) (b) P(x> 2)= (Round to the nearest thousandth as needed.) %3D (c) P(2sxs5)= (Round to the nearest thousandth as needed.)
