You can put this solution on YOUR website! b) Out of 6680 males, only 530 had Master's degrees. Which means that 6150 males DIDN'T have Masters. So 6150/6680= .92 probability
d)Of the 7196 females surveyed, only 52 had PhD's. So 52/7196= .00723 is the probability that a random female has a PhD ☺☺☺☺
