a)126 phd's/11089=.0113626
1-.0113626=.988637 probability selected person does NOT have a PhD.
b)737/11089=.06646
1-.06646=.9335 probability person does NOT have a Master's.
c)Total females + total Master's degrees=5672+737=6409
Less females with Masters degree=6409-352=6057
6057/11089=.5462 probability of female OR Masters degree.
d)Male or PhD=male + female PhD (Males with PhDs are already counted):
5417+57/11089=.4936 probability of male OR PhD degree. ☺☺☺☺
