Chapter 6.1, Problem 58E

Insurance: An insurance company sells a one-year term life insurance policy to an 80-year-old woman. The woman pays a premium of $1000. If she dies within one year, the company will pay $20,000 to her beneficiary. According to the U.S. Centers for Disease Control and Prevention, the probability that an 80-year-old woman will be alive one year later is 0.9516. Let X be the profit made by the insurance company. Find the probability distribution arid the expected value of the profit.
