First notice that we have 1/5 + 2/5 + 1/5 or 4/5 identified.
\n" ); document.write( "We are told that the rest, (1 -4/5)= 1/5 like all three subjects.\r
\n" ); document.write( "\n" ); document.write( "1/5 only biology
\n" ); document.write( "2/5 biology and math
\n" ); document.write( "1/5 biology, math,physics
\n" ); document.write( "So 4/5 like biology
\n" ); document.write( "
\n" );
