Female (F)Male (F′)Total
College degree (D) 27 23 50
No college degree (D′) 20 30 50
Total 47 53 100
Female OR college degree is each (97) minus both (27) or 70/100 or 0.70
Male or does not have is each (103) minus both (30) or 73/100 or 0.73
Female or does not have is each (97) minus both (20) 77/100 or 0.77
(Alternatively don't want male/college degree (23) so 1-0.23 or 0.77)
