Assuming all blood types are equally common, people with what blood types would have the best and worst odds of finding a donor?

Flexi Says: People with AB +ve blood group have the best odds of finding a donor as they can receive blood from people with all other common blood-types, regardless of the presence or absence of the Rh factor. People with O -ve blood type can receive blood only from an O-ve donor. They, therefore, have the worst odds of finding a donor.
