If there is a crossword that has three squares that need to be filled, how many possible three letter arrangements are there (assuming they do not have to make a real word)? A.26! B.26!/3! C.23! D.26!/23
26 possible letters assuming you can repeat them 26*26*26 no listed ok, lets assume that you can't repeat them that is 26 times 25 times 24 (because you used 1 each time) that is 26!/23! (because 26*25*24*23!=26!)
answer is D (only if there is a factorial sign after the 23)
