We report on the inclusive branching fractions of B{sup -} and of B-bar{sup 0} mesons decaying to D{sup 0}X, D-bar{sup 0}X, D{sup +}X, D{sup -}X, D{sub s}{sup +}X, D{sub s}{sup -}X, {lambda}{sub c}{sup +}X, {lambda}-bar{sub c}{sup -}X, based on a sample of 88.9x10{sup 6} BB-bar events recorded with the BABAR detector at the {upsilon}(4S) resonance. Events are selected by completely reconstructing one B and searching for a reconstructed charmed particle in the rest of the event. We measure the number of charmed and of anticharmed particles per B decay and derive the total charm yield per B{sup -} decay n{sub c}{sup -}=1.313{+-}0.037{+-}0.062{sub -0.042}{sup +0.063} and per B-bar{sup 0} decay n{sub c}{sup 0}=1.276{+-}0.062{+-}0.058{sub -0.046}{sup +0.066}, where the first uncertainty is statistical, the second is systematic, and the third reflects the charm branching-fraction uncertainties.
