Abstract
The charged multiplicity has been measured at the '(4S) and a value of 5.75±0.1±0.2 has been obtained for the mean charged multiplicity in B-meson decay. Combining this result with the measurement of prompt leptons from B decay, the values 4.1±0.35±0.2 and 6.3±0.2±0. 2 are found for the semileptonic and nonleptonic charged multiplicities, respectively. If b'c dominance is assumed for the weak decay of the B meson, then the semileptonic multiplicity is consistent with the recoil mass determined from the lepton momentum spectrum.
