In a certain year, 28.3% of all light vehicles were light trucks, 28.3% were SUVs, and 43.4% were cars. The probability that a severe side-impact crash would prove deadly to a driver depended on the type of vehicle he or she was driving at the time, as shown in the table. What is the probability that the victim of a deadly side-impact accident was driving an SUV? (Round your answer to four decimal places.) Light Truck SUV Car .210 .371...
