Option 2: Buy Toyota Corolla at 20000$ which gives a mileage of 33 miles/Gallon.
Robert is not sure about both the mileage and fuel price. The uncertainty of mileage is that of Table and Fuel price uncertainty follows beta distribution with pessimistic price being 3.92$/Gallon, most likely being 3.55$/Gallon and optimistic price being 3.01$/Gallon.
