WebThe approximate force of mortality is this probability divided by Δx. If we let Δx tend to zero, we get the function for force of mortality, denoted by : Since fX ( x )= F ' X ( x) is the probability density function of X, and S ( x) = 1 - FX ( x) is the survival function, the force of mortality can also be expressed variously as: To ... Web(a) Constant Force of Mortality and Constant Force of Interest: Consider a policy that pays $1 immediately at the death of the insured.
