Let X represent the amount of gas, in gallons, that drivers put in their cars when fueling at asmall downtown gas station. The model for this variable X is uniformly distributed between 4 and 12 gallons.

1) What is the probability that two randomly selected drivers fueling their cars at the downtown gas station will each put more than 10 gallons of gasoline in their cars?

2) A driver in the process of fueling the car at the downtown gas stationalready put 7 gallons of gasoline in the car and is not done yet. What is the probability that this driver will put more than 9 gallons of gasoline in the car?

For our uniform(4, 12) model, the standard deviation is 2.3094 gallons.
