We calculate the inclusive decaysB → X s Ψ andB → X s ν c using factorization assumption. To investigate the bound state effect of the decaying B meson in these inclusive decays we take into account the motion of theb quark using a Gaussian momentum distribution model. The resulting correction to free quark decay approximation is around 6% at most. Utilizing a potential model evaluation of the ratio of the decay constantsf νc 2/f Ψ 2, it is shown that the ratioR = Γ(B → X sνc)/Γ(B → XsΨ) can be used a possible test of factorization assumption.
