From the CME Chase Page at NASA (http://pwg.gsfc.nasa.gov/istp/nicky/cme-chase.html) :

Near solar activity maximum, the sun produces about 3 CMEs every day, whereas near solar minimum it produces only about 1 CME every 5 days.

That page also has a lot of interesting information about CME's, their mass, speed and their magnetic field. Well worth a read.
