Let f be a diffeomorphism of a compact finite-dimensional boundaryless mani
fold M exhibiting infinitely many coexisting attractors. Assume that each a
ttractor supports a stochastically stable probability measure and that the
union of the basins of attraction of each attractor covers Lebesgue almost
all points of M. We prove that the time averages of almost all orbits under
random perturbations are given by a finite number of probability measures.
Moreover, these probability measures are close to the probability measures
supported by the attractors when the perturbations are close to the origin
al map f.
