How common are different types of stars?

Question

Where can I find data on the relative commonality of different types of stars? 

I'm looking for something that will tell me what percentage of stars are red dwarfs, what percentage are ridiculously hot blue supergiants, etc. Or, to put it another way, a way to find out what the probability is that a randomly selected star would be of a certain type.

This will get you started. There is a very nice table partway down the page.

those probabilities from wikipedia may well be superb for the Milky way, in spite of if it relatively is impossible to declare precisely for the Universe, as stars in galaxies are unresolved gadgets (aside from the closest galaxies). there will be extra O and B stars in blue spirals galaxies than pink, elliptical galaxies, by using fact the mild emitted form those galaxies is predomidantly emitted via older stellar populations.
