Suppose you are playing a word game with seven distinct letters. How many seven letter words can there be?

Hint:Think about scrabble.
It is ok it the word is gibberish in this case
Answered by drwls
7! = 7*6*5*4*3*2*1 = 5040
You get a different (smaller) answer if some of the letters are the same.
