Let S be the universal set, where: S={1,2,3,...,18,19,20} Let sets A and B be subsets of S, where:? {
\n" ); document.write( "A={2,5,6,7,14,18,20}
\n" ); document.write( "B={1,3,4,5,7,8,9,10,11,17,20}
\n" ); document.write( "C={1,2,3,4,6,10,12,14,15,16,17,20} \r
\n" ); document.write( "\n" ); document.write( "Find the number of elements in the set (A∩C) ∩ B n[(A∩C)∩Bc]
\n" ); document.write( "----
\n" ); document.write( "(A and C) = n{2,6,14,20}
\n" ); document.write( "-----
\n" ); document.write( "(A and C) and B = {20}
\n" ); document.write( "B' = {2,6,12,13,14,15,16,18,19}
\n" ); document.write( "(A and C) and B' = {-}
