We obtain bivariate forms of Gumbel's, Fréchet's and Chung's linear inequalities for P(S≥ u, T≥ v) in terms of the bivariate binomial moments \Si,j\, 1≤ i≤ k, 1≤ j≤ l of the joint distribution of (S,T). At u=v=1, the Gumbel and Fréchet bounds improve monotonically with non-decreasing (k,l). The method of proof uses combinatorial identities, and reveals a multiplicative structure before taking expectation over sample points.
