The number of permutations of the letters of the word 'MESMERISE' is?  Pick:
A) 9!/(2!)2 3!  B) 9!/(2!)2 8!  C) 9!/(8!)2 3!  D) 8!/(2!)2 3!  E) 9!/(2!)2 1!
n items of which p are alike of one kind, q alike of the other, r alike of another kind and the remaining are distinct can be arranged in a row in n!/p!q!r! ways.   The letter pattern 'MESMERISE' consists of 10 letters of which there are 2M's, 3E's, 2S's and 1I and 1R.   Number of arrangements = 9!/(2!)2 3!   9!/(2!)2 3!nswer: 9!/(2!)2 3!
