You can put this solution on YOUR website!
I'll help you find A', B', and C' and let you finish the rest. Repost if you need more help.\r

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "To find A', simply list all of the elements of U that are NOT in A. In other words, you're listing elements that are NOT in A. So\r

\n" ); document.write( "\n" ); document.write( "\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Likewise, to find B', list the elements of U that are NOT in B. This means..\r

\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now all you need to do is find (just combine sets A' and C') and (take the last set and intersect it with set B')
\n" ); document.write( "
\n" );
