We report on the inclusive branching fractions of B- and 
of B0bar mesons decaying to 
D0 X, Dbar0 X, D+ X, D- X, 
Ds+ X, Ds- X, Lambdac+ X, Lambdabarc- X, 
based on a sample of 88.9 million BBbar 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 anti-charmed 
particles per B decay and 
derive the total charm yield per B- decay, 
n_c- = 1.313 +/- 0.037 +/- 0.062 {+0.063}{-0.042}, 
and per Bbar0 decay, 
n_c0 = 1.276 +/- 0.062 +/- 0.058 {+0.066}{-0.046}
where the first uncertainty is statistical, 
the second is systematic, and the third reflects the charm 
branching-fraction 
uncertainties.
