We analyze 9.7 X 10(6) B (B) over bar pairs recorded with the CLEO detector to determine the production ratio of charged to neutral B-meson pairs produced at the Y(4S) resonance. We measure the rates for B-0 --> J/psiK((*)0) and B+ --> J/psiK((*)+) decays and use the world-average B-meson lifetime ratio to extract the relative widths f(+-)/f(00) = Gamma (Y(4S)-->B+B-)/Gamma (Y(4S)-->B-0(B) over bar (0)) = 1.04 +/- 0.07(stat) +/- 0.04(syst). With the assumption that f(+-) + f(00) = 1, we obtain f(00) = 0.49 +/- 0.02(stat) +/- 0.01(syst) and f(+-) = 0.51 +/- 0.02(stat) +/- 0.01(syst). This production ratio and its uncertainty apply to all exclusive B-meson branching fractions measured at the Y(4S) resonance.
