Find the difference between the number of elements in the union and the intersection of the following sets:\r
\n" ); document.write( "\n" ); document.write( " M = {2, 4, 6, 8, 10, 12} and N = {1, 3, 5, 7, 9, 11}\r
\n" ); document.write( "\n" ); document.write( "the union is : M U N= {2,4,6,8,10,12} U {1,3,5,7,9,11}={1,2,3,4,5,6,7,8,9,10,11,12}\r
\n" ); document.write( "\n" ); document.write( "the number of elements in union is \"12\"\r
\n" ); document.write( "\n" ); document.write( "the intersection is: M ∩ N= { 0 }...there is no same elements in the set M that belong to set N \r
\n" ); document.write( "\n" ); document.write( "so, the cardinality (count of elements in a set) is \"zero\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "and answer to your question, the difference between the number of elements in the union and the intersection of the following sets: M = {2, 4, 6, 8, 10, 12} and N = {1, 3, 5, 7, 9, 11}, is \"12-0=12\"
\n" ); document.write( " \n" ); document.write( "
