Suppose that the handedness of the last fifteen u. s. presidents is as follows: 40% were left-handed (l) 47% were democrats (d) if a president is left-handed, there is a 13% chance that the president is a democrat. based on this information on the last fifteen u. s. presidents, is “being left-handed” independent of “being a democrat”? no, since 0.40 is not equal to 0.13. yes, since 0.40 * 0.47 is not equal to 0.13. yes, since 0.47 is not equal to 0.13. no, since 0.47 is not equal to 0.13.

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?
