Hi  

Education Level	       Male	Female	Total

High School or Less	2136	2409	4545

Bachelor's Degree	2827	2854	5681

Master's Degree	         385	352	737

Ph.D.	                 69	57	126

Total	                5417	5672	11,089

a) P(NOT PhD) = 1 - P(PhD) = 1 - 126/11,089

b) P(NOT Masters) = 1 - P(M) = 1  - 737/11,089

c) P(F 0r Masters) = (F) + (Masters) - (Both) = 5672/11089 + 737/11089 - 352/11089

d) P(M 0r PhD) = (1/11089) [(5417) + (126) -(57)]
