Question 1164720
<font face="Times New Roman" size="+2">


If *[tex \Large \frac{3}{4}] of the 52 unmarried are college graduates, then 39 are both unmarried and college graduates.  Then 52 minus 39 = 13 are unmarried and not college graduates and 72 minus 39 = 33 are college graduates that are not unmarried.  So 13 + 39 + 33 are either unmarried, college graduates, or both.  The rest of the 150, you do the arithmetic, are both not unmarried and not college graduates.


However, you cannot answer this question with the information given.  Just because a person is unmarried doesn't mean they are single.  So know the number of unmarried out of a particular group allows you to figure the number that are married, but you cannot figure the number that are not single.  If your instructor made up this question or gave it to you after s/he read it, then you are not being taught by a mathematician.  If you are paying tuition, I would ask for a refund.
