Each year, United Parcel Service (UPS) commissions a "Pulse of the Online Shopper" survey. The 2015 survey included a sample of 5,118 U.S. shoppers who have made at least two online purchases every three months. The survey revealed that 41% of the shoppers used a smart phone to make a purchase. Of those who made a smart phone purchase, 38% indicated that they preferred the mobile Web site to the full Web site accessed through a computer. Assume these percentages represent actual probabilities for the population of online shoppers. What is the probability that a randomly selected online shopper uses a Smartphone to make a purchase and prefers the mobile Web site?
