A simple question (but one to which I didn't find an answer in several astronomy books): how are the stars distributed per spectral class? I. e. which percentages of stars are O stars, B stars, ... , K stars, M stars?
Anyone can help me to answer. thanks!

What about this table (https://en.wikipedia.org/wiki/Stellar_classification#Harvard_spectral_classifica tion) on Wikipedia?
