We examine the three-body baryonic $\bar B\to {\bf B\bar B'}V$ decays with $V$ vector mesons in the standard model. We can simultaneously explain the recent experimental data on the decays of $B^-\to \Lambda\bar p \,\rho^0$ and $\bar B\to \Lambda\bar \Lambda \bar K^{*}$ based on the QCD counting rules and SU(3) flavor symmetry. We also predict that the decay branching ratios of $\bar B^0\to \Lambda\bar p \,\rho^+$ and $B^-\to \Lambda\bar p \,\phi$ are 3.0 and $1.5\times 10^{-6}$, respectively, which are promising to be observed by BELLE and BABAR at the $B$ factories.
