\label{fig:quiescent_fraction}  For all observed satellites  dwarf galaxiesthat are satellites  within $300\kpc$ of the Milky Way (MW) or Andromeda (M31), the fraction that are quiescent ($\mgas/\mstar<0.1$) versus stellar mass, $\mstar$. Blue circles show all satellites,while  violet squares (green triangles)  show those of just  the MW and green triangles show those of M31. (M31).  The only star-forming/gas-rich satellites are: LMC ($\mstar=1.5\times10^9\msun$) and SMC ($\mstar=4.6\times10^8\msun$) around the MW, LGS 3 ($\mstar=9.6\times10^5\msun$) and IC 10 ($\mstar=9\times10^7$) around M31.  At $\mstar<8\times10^7\msun$, 50 of 51 satellites are quiescent, and at $\mstar<9 \times10^5\msun$ $\mstar<9\times10^5\msun$  \emph{all} are quiescent. The error Error  bars show 68\% uncertainty for a beta distribution \citep{Cameron2011} based on the observed counts.
