In this paper, uncertain belief representation by using probability is investigated. The representation equivalence between interval probability suggested by D.D. Phan (1990) and convex set of probability distribution by H. Kyburg (1990) is proved. Probabilistic closures using classical and relevant consequence relations are defined and compared. Their agreement on a non-tautological fragment is proved.
