You can put this solution on YOUR website!
P(drawing a 4) = 1/7\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "once a 4 is drawn (and not put back), there are 6 cards left. So \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "P(drawing a 6 next) = 1/6\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So ...\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "P(drawing a 4 then a 6) = P(drawing a 4) * P(drawing a 6 next) = (1/7)*(1/6) = (1*1)/(7*6) = 1/42
\n" ); document.write( "
\n" );
