(iii) Deaths are uniformly distributed over each year of age. Calculate Emma 4. A whole life insurance of 50 is issued to (x). The benefit is payable at
the moment of death. The p.d.f. of the future lifetime, T, for (x) is l/\ f(t) = t/5000, 0 g t _ 100
The force of interest is 0.1. Calculate the net single premium. 5. There are 100 club members age x who each contribute an amount N to a
fund. The fund earns interest at 10%. The probability is 0.95 that
sufficient funds will be on hand to pay a 100 death benefit to each member.
