A={1,2,3}
\n" ); document.write( "B={3,4,5,6}
\n" ); document.write( "C={3,5,7}
\n" ); document.write( "Union is all elements of both sets.
\n" ); document.write( "Intersection is only the common elements to both sets.
\n" ); document.write( "a)A ∩ B = (3)
\n" ); document.write( "b)A ∩ C = (3)
\n" ); document.write( "c)A U C = (1,2,3,5,7)
\n" ); document.write( "d)B U C = (3,4,5,6,7)
\n" ); document.write( "e)(A U B) ∩ C=(1,2,3,4,5,6)∩(3,5,7)=(3,5)
\n" ); document.write( "f)A U (B U C)=A U (3,4,5,6,7)=(1,2,3,4,5,6,7)
\n" ); document.write( "g) (A ∩ B) ∩ C=(3)∩ C=(3)
\n" ); document.write( "h) (A ∩ B) U C=(3)U C=(3,5,7)
\n" ); document.write( "
\n" );
