In our study, we find that ${\\cal A}_{FB}[\\bar B^0\\to\\Lambda\\bar p \\pi^+(B^-\\to \\Lambda\\bar p\\pi^0)]$ can be as large as $(-14.6^{+0.9}_{-1.5}\\pm 6.9)\\%$. In addition, we present ${\\cal A}_{FB}[\\bar B^0\\to\\Lambda\\bar p \\rho^+(B^-\\to \\Lambda\\bar p\\rho^0)] =(4.1^{+2.8}_{-0.7}\\pm 2.0)\\%$ as the first prediction involving a vector meson in the charmless $B\\to{\\bf B\\bar B'}M$ decays.
