We reanalyze the question of the frequency of symbiotics in the Galaxy, notice that their discovery probability so far has been grossly overestimated, and derive under conservative assumptions a total number for them of about 3 x 10 exp 5, some 100 times more than currently reported. It follows that to account for the observed frequency of SN Ia's in the Galaxy it is sufficient that only about 4 percent of these symbiotics conclude their evolution with the accreting white dwarf reaching the Chandrasekhar limit and exploding as a supernova.
