A study is made of systems of Lipschitz-continuous mappings which are applied successively on an initial point x0 in a closed, nonempty, complete metric space. All mappings possess the same fixed point x*, and are applied at random with repetitions by choosing a mapping from a finite set of such functions. A lower bound is found on the probability that the system's state after n iterations, xn, is within a ρ-neighborhood of the common fixed point, x*. Conditions are developed that guarantee that the lower bound is (eventually) monotonically increasing in n.
