You can put this solution on YOUR website! a) Total PhD's out of 11089 working adults were 126. Therefore, the probability that a randomly selected person does NOT have a PhD is 1-126/11089, or .988637.
b)Total Masters degree holder were 737/11089, so 1-737/11089=.9335377 is the probability of NOT selecting a Masters holder.
c)Females, or Masters degrees is 5672+737-352(both female and Masters degree)/11089= .5462170.
d)All males + female PhDs (male PhDs would be counted twice) is 5417+57/11089=.4936423. ☺☺☺☺
