Radial velocities, with precisions better than 0.40 km/sec have been obtained for a random sample of 40 K giant stars. The frequency os spectroscopic binaries detected in this sample from observations over a 3 year time span is 15% to 20%, and more are probably long-period binaries. A comparison is made between this sample and others including the sample of giants measured by Gunn and Griffin (1979) in the globular cluster M3. The comparison with M3 indicates that, when allowance is made for the sizes and masses of the stars, there is no evidence from published velocity data that M3 is deficient in binaries.
