4. (a) Explain the difference between Insurances payable at the moment of death and those payable at the end of year of death, using the relevant random variables. (b) What is an M-year Deferred Life Insurance Plan, payable at the end of the year of death. What is it's present value random variable. (c) Let the remaining lifetime at birth random variable X be uniform on (0,100]. Let 10/230 be the contingent payment random variable for a life aged x = 30. How much should an insured person on this plan pay to receive a benefit of 10,000GHC at the end of his year of death.(Asssuming he satisfies all relevant conditions.) 4.
