document.write( "1.  The given word  NEIGHBOUR  has 9 letters, all of them are different.\r\n" );
document.write( "\r\n" );
document.write( "    From 9 different letters, you can make 9*8*7 = 504 different 3-letter words.\r\n" );

document.write( "2.  The word  NEIGHBOUR  has 4 vowels, all of them are different.\r\n" );
document.write( "\r\n" );
document.write( "    From 4 different vowels, you can make 4*3*2 = 24 different 3-letter words consisting of 3 vowels each.\r\n" );
