Exercises: Evaluate and Compare Strategies Using Expected Values

Work through each section in order. For every comparison, FIRST state the direction: an expected COST means lower is better; an expected PAYOFF means higher is better. Model each strategy as its own distribution, compute its expected value, then compare the totals. For insurance problems, remember expected cost = premium + expected out-of-pocket. Show your arithmetic.

Compute each strategy's expected value and compare. State the direction.

1.

An auto policy has a $1,200\text{\char"0024}1{,}200 annual premium and a $250\text{\char"0024}250 deductible paid per accident. For this driver the chance of having at least one accident (which triggers the full deductible) is 0.150.15. The expected annual cost is the premium plus the expected out-of-pocket payment. Compute the expected annual cost, in dollars.
