The proportion of cars that exceed the speed limit in a particular highway is 0.05. Speed radars are available to determine whether a car actually exceeded the limit or not. If the speed limit is exceeded, with 0.92 probability, the electronic radar system will send a penalty ticket to driver's home address. However, in 2% of the cases, the drivers get a ticket when they actually did not exceed the limit. Given that a driver has received a ticket, the probability that s/he actually exceeded the speed limit is (Round to three decimal places, including any zeros at the end.)
