total ways of selecting two students is $\"23c2\"$
\n" ); document.write( "favorable ways are $\"11c2\"$
\n" ); document.write( "so the probability that both students will be males = $\"%2811c2%29%2F%2823c2%29\"$
\n" ); document.write( "
\n" ); document.write( " = 5/23 ans\r
\n" ); document.write( "\n" ); document.write( "another way of answering\r
\n" ); document.write( "\n" ); document.write( "prob. that first student is male = 11/23
\n" ); document.write( "prob. that second student is male = 10/22\r
\n" ); document.write( "\n" ); document.write( "so the probability that both students will be males=(11/23)*(10/22)\r
\n" ); document.write( "\n" ); document.write( " =5/23 \n" ); document.write( "

\n" );
