10) A college student is about to purchase a car when the salesman recommends that he should sign up for a protection plan. Under this plan, the student will pay an additional 'AA per month to cover the costs of oil changes, routine maintenance, and any major repairs. The protection plan provides coverage for the first five years of ownership. On average, the student drives 12,000 miles per year. He is very responsible and will get an oil change every 5000 miles. The average cost of an oil change is $30. A) What is the cost of oil changes for the first five years if the student does not accept the protection plan and pays for his own oil changes? B) In the probability distribution below, you can see the potential cost of routine maintenance and possible major repairs in the first five years of car ownership. Oil changes are not included in the cost. annual Maintenance & Repair cost for the 0 $500 $1000 $1500 $2000 1st five years, (x) Probability, P(x) 0.19 10.67 0.09 0.04 0.01 X*P(x) What is the expected cost of routine maintenance and possible major repairs for the first 5 years? Note the expect cost is the mean cost (the sum of the last row.)
