"The market returns are 15%, 9% and 18% and Stock J returns are 20%, 5% and 12% . They have the probability distributions 0.3, 0.4 and 0.3 and expected returns are: Market: 13.5% and Stock J: 11.6%. Standard deviation are: Market: 3.85% and Stock J: 6.22%. Calculate the coefficients of variation for the market and Stock J."

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?
