\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "6 choices for slot 1
\n" ); document.write( "5 choices for slot 2 (6-1 = 5)
\n" ); document.write( "4 choices for slot 3 (6-2 = 4)\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Which means that there are 6*5*4 = 30*4 = 120 different 3 digit numbers to form (without repetition).
