B 5 s 5 B > s 5 individual bought the item singular saw the notice individual bought the item and saw the notice The probabilities appointed were P(B) = .20, P(S) = .40, and P(B S) = .12. a. What is the likelihood of a person's buying the item given that the individual saw the ad? Does seeing the promotion increment the likelihood that the individual will buy the item?

The organization likewise tried another notice and doled out it estimations of P(S) = .30 and P(B S) = .10. What is P(B S) for this other notice? Which promotion appears to have had the greater impact on client buys?
