Results are presented of a study of opposite-sign dimuon events observed in a fine-grained neutrino detector exposed to the Fermilab Tevatron wide-band neutrino beam. A total of 300 background-corrected {mu}{sup +}{mu}{sup {minus}} events induced by incident neutrinos and antineutrinos with energies up to 500 GeV were accumulated. The data were analyzed in terms of a model based on charm-quark production followed by semileptonic decay of the charmed meson. The Cabibbo-Kobayashi-Maskawa matrix terms were found to be {vert bar}{ital U}{sub {ital c}{ital d}}{vert bar}{sup 2}=0.0378{plus minus}0.0127 (stat){sub {minus}0.0082}{sup +0.0099} (syst), and {kappa}{vert bar}{ital U}{sub {ital c}{ital s}}{vert bar}{sup 2}=0.391{plus minus}0.076 (stat){sub {minus}0.066}{sup +0.097} (syst). The ratio of the strange to nonstrange sea in the nucleon, {kappa}=2{ital S}/({ital {bar U}}+{ital {bar D}}), was measured to be 0.407{plus minus}0.075 (stat){sub {minus}0.069}{sup +0.103} (syst).
