For the oldest man but not the oldest women, one is chosen, and if a man, there are 10 left, since the woman can't be chosen. It is 10 choose 7, because one has already been chosen.
\n" ); document.write( "10C7=720/6=120.
\n" ); document.write( "Now do it with the oldest woman but not the oldest man, and again there are 10 left, and now choose 7.
\n" ); document.write( "There are another 120 committees, this time with the oldest woman.
\n" ); document.write( "The sum is 240 committees. \n" ); document.write( "

\n" );
