1.) A gasoline tank for a certain model car is designed to hold 12 gallons of gas. Suppose that the actual capacity of the gas tank in cars of this type is well approximated by a normal distribution with mean= 12.0 gallons and a standard deviation of 0.2 gallons.

If you randomly select one car of this model, what is the probability that the car's gas tank holds at most between 11.9 and 12.2 gallons?
