In a 10 man race, how many runners have the chance to finish first?\r
\n" ); document.write( "\n" ); document.write( "answer 10.\r
\n" ); document.write( "\n" ); document.write( "Now that 1 person is first, how many runners could be second? Well, there are still 9 runners left, and any one of hem could be second. \r
\n" ); document.write( "\n" ); document.write( "Answer 9.\r
\n" ); document.write( "\n" ); document.write( "How many can be third? Using the same idea as above, once one person is first and another is is second, that leaves 8 people still running and trying for third. So how many can be in third?\r
\n" ); document.write( "\n" ); document.write( "Answer 8.\r
\n" ); document.write( "\n" ); document.write( "Now you need to do the math\r
\n" ); document.write( "\n" ); document.write( " $\"10+%2A+9+%2A+8+=+720\"$
\n" ); document.write( "So there are 720 different ways \n" ); document.write( "

\n" );
