Of the 17-year-old persons who hold a driver's license, 85% have had a driver's ed course, and 15% have not. The probability of a 17-year-old student with a driver's license who has had driver's ed being involved in an accident is 0.3 and the probability of a 17-year-old driver with a driver's license who has not had driver's ed being involved in an accident is 0.54. A 17-year-old driver is involved in an accident. Find the probability that the driver has had driver's ed. (Round your answer to three decimal places.)
