You can put this solution on YOUR website!
U = { 1,2,3,4,5,6,7 }, A = { 1,2,5,7, } , B = { 1,4,5 } What is the set A'⋂B'?
\n" ); document.write( "

\r\n" );
document.write( "A' is the set of all elements in U which are not elements of A.\r\n" );
document.write( "So A' = { 3,4,6 }\r\n" );
document.write( "\r\n" );
document.write( "B' is the set of all elements in U which are not elements of B.\r\n" );
document.write( "So B' = { 2,3,6,7 }\r\n" );
document.write( "\r\n" );
document.write( "So A'⋂B' = { 3,4,6 } ⋂ { 2,3,6,7 }\r\n" );
document.write( "\r\n" );
document.write( "The intersection contains only the elements that are in common\r\n" );
document.write( "to both sets, which are 3 and 6, so\r\n" );
document.write( "\r\n" );
document.write( "A'⋂B' = { 3,4,6 } ⋂ { 2,3,6,7 } = { 3,6 }\r\n" );
