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)

Idk idk idk idk idk idk idk idk

Think of it as five or above give it a shove. change the 5 or above to the right to a zero and add one to the number on the left.
