To determine what effect the salespeople had on purchases, a department store polled 700 shoppers as to whether or not they had made a purchase and whether or not they were pleased with the service. Of those who had made a purchase, 120 were happy with the service and 113 were not. Of those who had made no purchase, 149 were happy with the service and 318 were not.

Find the probability that a shopper who was happy with the service had made a purchase (round off to the nearest hundredth).

What can you conclude? (Round your answer to the nearest whole number.)
