For a prime p and positive integer n, let Zp(n) and Psi(Z(p)(n)) denote the ring of integers modulo p(n) and the directed graph associated with the ring Zp(n), respectively. In this paper, we obtain an explicit formula for determining the number of non-sources in the directed graph Psi(Zp(n)). This formula may then be used to determine the number of non-sources in the directed graph Psi(Z(m)) where m is a positive integer.
