You did not say Decimal 0r Fraction????
(a) What is the probability that the selected person does not have a Ph.D.?
P = 1 - 106/13604 = 13498/13604 = 6749/6802
(b) What is the probability that the selected person does not have a Master's degree?
P = 1 - 975/13604 = 12629/13604
(c) What is the probability that the selected person is female or has a Master's degree?
P = (7571 + 975 - 502) / 13604 = = 8044/13604= 2011/3401
(d) What is the probability that the selected person is male or has a Ph.D.?
P = (6033 + 106 - 60)/13604 = 6079/13604
