The table shows the number of cars and trucks that used a certain toll road on a particular day. The number of cars and trucks that used, and did not use, an electronic toll pass on that same day was also recorded. Toll Pass Used Did not use Total Cars 517 938 1455 Trucks 310 645 955 Total 827 1583 2410 Q a) If one of these vehicles is selected at random, determine the probability that the vehicle used a toll pass. b) If one of these vehicles is selected at random, determine the probability that the vehicle used a toll pass given that the vehicle was a truck. The probability that the randomly selected vehicle used a toll pass is (Round to four decimal places as needed.) The probability that the vehicle used a toll pass, given that the vehicle is a truck, is (Round to four decimal places as needed.)
