P(all your female bossses awful) = P(awful boss)^(number of female bosses)
P(all your male bossses awful) = P(awful boss)^(number of male bosses)
The lower the number of male/female bosses, the greater the probability of all of them being awful. The opposite (probability of all of them being not awful) increasing is also true.
This is generally known as a small numbers fallacy[1]
