Well this is an interesting problem because Cathy has to turn on the lights eventually to find out if she actually has a pair of socks or not.
\n" ); document.write( "6 pair of white=12 white
\n" ); document.write( "6 pair black=12 black
\n" ); document.write( "if she pulls one white then one black she doesn't have a pair.
\n" ); document.write( "if she pulls one black and then one white she does not have a pair.
\n" ); document.write( "but the next sock will make a pair either a black pair or white pair.
\n" ); document.write( "But what good will it do her since she most likely has only two feet and will have three socks.
\n" ); document.write( "So after she has the three socks she has to turn on the lights to see which two actually do match.
\n" ); document.write( " \n" ); document.write( "

\n" );
