According to The Motorist, a publication of the American Automobile Association, 90% of all calls for emergency service on a cold winter day in Flagstaff are for cars that won’t start because of a dead battery, 10% of the calls are for cars that won’t start because they have no gas, and 4% of the calls are for cars that won’t start because of a dead battery and no gas. If a typical call is randomly selected, what is the probability that it is for a car that won’t start because of a dead battery or because of no gas?
