Question: Let X be the amount of premium gasoline in 1 000
Let X be the amount of premium gasoline (in 1,000 gallons) that a service station has in its tanks at the beginning of a day, and Y the amount that the service station sells during that day. If the joint density of X and Y is given by
Use the distribution function technique to find the probability density of the amount that the service station has left in its tanks at the end of the day.
