This implies that for every element x associated with a sample space, all probabilities must be positive. ∑xϵSf (x) = 1 ∑ x ϵ S f ( x) = 1. The sum of all probabilities associated with x values of a discrete random variable will be equal to 1. In D-S evidence theory, a mass function is also called a basic probability assignment (BPA). Suppose m 1 and m 2 are two independent BPA in the frame of discernment X, Dempster's rule of combination, denoted by the form m = m 1 ⊕ m 2, is defined as:. Poisson distribution. value.
