Katrina pose la question :
A term life insurance policy will pay a beneficiary a certain sum of money upon the
death of the policy holder. These policies have premiums that must be paid annually. Suppose a
life insurance company sells a $250,000 one-year term life insurance policy to a 20-year-old male
for $350. According to the National Vital Statistics Report, Vol. 47, No. 28, the probability the
male will survive the year is 0.99865. Compute the expected value of this policy to the insurance
company. Does the company expect to make money at this rate?
