Question
Consider a two-decrement model where active policyholders can leave the active state due
to either death or sickness. At a given age x, the independent probability of death is
q = 0.5, whereas the independent probability of sickness is qž = 0.6. Under the
assumption of independence of decrements, which of the following is the correct value of
the dependent probability of remaining in the active state, i.e. (ap)x?
O a. (1 – 0.5) + (1 – 0.6) = 0.9.
0.5
Ob.
x (1 – exp(-(0.5 + 0.4)) z 0.33.
0.5+0.4
O c. 0.5 × 0.4 = 0.2.
O d. 0.5 x 0.6 = 0.3.
