\n" ); document.write( "I should have used combinations instead of permutations since order does not matter\r
\n" ); document.write( "\n" ); document.write( "small pizza: 8C3=336/6=56
\n" ); document.write( "medium pizza: 8C4=1680/24=70
\n" ); document.write( "large pizza: 8C5=6720/120=56\r

\n" ); document.write( "\n" ); document.write( "these answers do not make sense!
\n" ); document.write( "--
\n" ); document.write( "for the small pizza there are 8P3=8*7*6=336 different types of small pizzas
\n" ); document.write( "for the medium pizza there are 8P4=8*7*6*5=1680
\n" ); document.write( "for the large pizza there are 8P5=8*7*6*5*4=6720
