Hi

         HS<4  HS=4  C<4   C≥4  Total

males    14    25    20     23  82

females  15    31    24     22  92

 total      29    56    44     45  174

1. P(has not completed 4 yrs (or more) of college) = 129/174

2. P(has not completed 4 yrs of high school) = 29/174

3. P(has completed four years of high school only 'or' less than 4 years of college) 56/174 + 129/174 - 56/174

4. P(has completed less than 4 yrs of high school or four years of high school only)= 29/174 + 44/174 - 29/174 

5. p(has completed 4 yrs of high school only 'or' is a man) 56/174 + 82/174 - 14/174. 

6. P(has completed 4 years of high school only or is a woman)= 56/174 + 92/174-31/174
