A police checkpoint is set up on New Years Eve to catch drunk drivers. It is known that 8% of drivers on New Years Eve have a blood-alcohol level that is above the legal limit. It is also known that 32% of drivers in the area never drink and drive, but are simply bad drivers. The remaining 60% of drivers never drink and drive and are good drivers. At this particular checkpoint, the police stop 85% of the drunk drivers, stop 38% of the bad drivers, and stop 2% of the good drivers. (a) There are four key events in this problem. Specify the four key events and define notation for each of them. (b) What is the probability that a randomly selected driver will be stopped at the checkpoint? (c) What is the probability that a driver who is stopped at the checkpoint is drunk?
