Customers are used to evaluate preliminary product designs. In the past, 95% of highly successful products received good reviews, 60% of moderately succesful 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 probabitliy that it will be 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?
d) Is "a product is poor" independent of "a product receives a good review"? Justify your answer with a mathematical test as well as with a statement of logic.
If any of them can be answered, I am very thankful. Please show your work for me to see. Thank you.
