How many arrangements are possible using the letters in the word FUZZY if each letter “Z” is distinctly different than the other? How many arrangements are possible if the letter “Z” is interchangeable with the other? I know that the first question is 5!, but I do not understand the second.

since in the second one you cannot tell the Z apart, and since there are two of them, it is \[\frac{5!}{2!}\]

Thanks!
