Insurance: An insurance company sells a 1-year term life insurance policy to an 80-year-old woman. The woman pays a premium of 54,000 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 1 year later is 0.9398. Let X be the profit made by the insurance company.Part: 0 / 20 of 2 Parts CompletePart 1 of 2(a) Find the probability distribution.The probability distribution is
Solution
The probability distribution of the profit made by the insurance company can be calculated as follows:
There are two possible outcomes for the insurance company:
-
The woman survives the year: This event has a probability of 0.9398. In this case, the company makes a profit of $3300 (the premium paid by the woman).
-
The woman dies within the year: This event has a probability of 1 - 0.9398 = 0.0602. In this case, the company pays out 54,000 - 50,700.
So, the probability distribution of X (the profit made by the insurance company) is:
- X = $3300 with a probability of 0.9398
- X = -$50,700 with a probability of 0.0602
