• 1. Expected Value of Life Insurance

The table shows the probabilities of dying during the year for various ages.

A 23-year-old male pays \$275 for a 1-year \$150,000 life insurance policy. What is the expected value of the policy for the policyholder? (See Example 1 and Example 2.)

• Worked-Out Solution

It makes sense that the expected value is negative. Remember that this is from the point of view of the policyholder. This means that the expected value for the insurance company is positive. Another way to think of this is that the insurance company can expect to earn about \$50 for each 23-year-old male that buys a 1-year \$150,000 policy.
