prep question

by jamesk486 » Sun May 13, 2007 2:24 am
In a school, there are people majoring in art and also in medicine. People majoring in art are 40%, people who major in medicine are 46%. What part of the school are those who major in art but not in medicine?
(1) people who major in both are 30%
(2) people who major in neither are 26%

==> i know its a pretty easy answer but just want to make sure how you solve for each condition :)
