13. In modeling the number of claims filed by an individual under an automobile policy during a three-year period, an actuary makes the simplifying assumption that for all integers n ≥ 0 , p ( n+1)=0.2p(n) where p(n) represents the probability that the policyholder files n claims during the period.
