Let(Ω,F, P)be a non-atomic probability space. For a given sequence (X_n)of random variables we indicate a number of conditions whichimply that for anyrandom variable Y there exists a sequence(U_n) of σ-fields satisfying E(X_n|U_n)→Ya.s. In particular, we formulate a sufficient condition using the distributions of X_n’sonly.
