I think the following figures are roughly correct: One of the sources of gamma ray bursts may be the merger of orbiting black hole - neutron star pairs in other galaxies, and perhaps about a hundred of these occur annually. If about 1% of this number is the merger of orbiting black hole - black pairs, then about one of these observable BH-BH mergers should occur annually.
