Question 729490: Q.two stores sell a certain product. Store A has 36% of the sales, 2% of which are defective items, and store B has 64% of the sales, 1% of which are defective items. The difference in defective rates is due to different levels of pre-sale checking of the product. A person receives one of this product as a gift. What is the probability it is defective?
