2,000 pairs of independent lives each purchase 5-year term assurance contracts paying 15 immediately on death of the lives. The insurer charges the same single premium for each contract. Use a normal approximation to calculate the single premium required such that the probability that the insurer makes a loss on the entire portfolio of 2,000 contracts is 5%. The interest rate is 6% and the death probability is 0.06 for all ages.
