\n" ); document.write( "\n" ); document.write( " The original formulation is INCORRECT and nonsensical, since the number of red balls is just GIVEN.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " To make sense, the problem MUST BE RE-FORMULATED. For example, in THIS WAY :\r
