\n" ); document.write( "Part (a)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "There are 9 choices in the first slot, then 8 for the next, and so on. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "9*8*7*6*5*4*3*2*1 = 362,880 different ways to arrange the letters of FACETIOUS.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "For more information, search out \"factorial\".\r

\n" ); document.write( "\n" ); document.write( "Part (b)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "I'm assuming the \"5\" should be \"S\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "We have F locked in the first slot and S locked in the last slot.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "There are 2 letters locked in place.
\n" ); document.write( "That leaves 9-2 = 7 letters left to arrange in 7 slots.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "7*6*5*4*3*2*1 = 5,040 different ways to arrange the letters of FACETIOUS such that the \"word\" begins with F and ends with S.
