title: How do i simplify f = x'yz + xy'z + xyz'?
body: <p>I am working on simplifying the expression <code>f = x'yz + xy'z + xyz' + xyz</code>. Actually, it may not be this expression. The question is: simplify the boolean expression for a voting system, the system being: three people vote on multiple candidates, and two or more people should agree(true) on the candidate in order to pass. So I think the answer would be <code>xy + yz + xz</code>, but I can't figure out the process between. Can anyone explain?</p>
