Combination Problem

Question

A word of 16 letters is selected: ALMOSTIMPOSSIBLE

 

a) How many different words are possible if the first and last letters are the same?

b) How many different words are possible if A,L and M are used together in any order?

 

Answer 1

Your question is a little vague. What are the conditions under which a) and b) are to be answered? Are the same letters as in the original word to be used, or are any letters permitted?

 

If you could clarify more and be more precise in your phrasing of this question, it might help get an answer sooner.
