Master's Degree	         473	502	975

Ph.D.	                  60	46	106

Total	               6033	7571	13,604

A person is selected at random. Compute the following probabilities.

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
