The b → ccs transition is usually believed to hadronize predominantly in B → XcDs(*)- with the Ds(*)- originating from the virtual W. We demonstrate in a variety of independent ways that other hadronization processes cannot be neglected. The invariant mass of cs has sizable phase-space beyond md + mk. The rate for B → DDKX could be significant and should not be ignored as was done in previous experimental analyses. We estimate the number of charmed hadrons per B-decay, nc, to be ≈ 1.3 to higher accuracy than obtained in previous investigations. Even though nc is currently measured to be about 1.1, observing a significant B → DDKXwould support nc ≈ 1.3. Many testable consequences result, some of which we discuss.
