\n" ); document.write( "\n" ); document.write( "In a class of $\"16\"$ students, \r
\n" ); document.write( "\n" ); document.write( "if $\"13\"$ students took a Math test, so far $\"3\"$ students did not take a Math test\r
\n" ); document.write( "\n" ); document.write( "if $\"10\"$ students took Science test, and $\"9\"$ students took both tests, then there was $\"1\"$ student who took Science test only\r
\n" ); document.write( "\n" ); document.write( "so, if $\"13\"$ students took a Math test and $\"1\"$ student who took Science test only, means $\"14\"$ students took either a Math test or Science test or both\r
\n" ); document.write( "\n" ); document.write( "so $\"16-14=2\"$ students did not take any of the tests \n" ); document.write( "

\n" );
