A survey carried out for a supermarket classified customers according to whether their visits to the store are frequent or infrequent and whether they often, sometimes, or never purchase generic products. The accompanying table gives the proportions of people surveyed in each of the six joint classifications. Complete parts (a) through (h). Purchase of Generic Products Frequency of Visit Frequent Often Sometimes Never 0.17 0.19 0.39 Infrequent 0.04 0.16 0.05 a. What is the probability that a customer is both a frequent shopper and never purchases generic products? 0.17 (Do not round.) b. What is the probability that a customer who sometimes buys generic products visits the store frequently? (Round to four decimal places as needed.)
