## Homework Statement

How many anagrams with 4 distinct letters and that have two of the letters "a", "b" and "c" can you make using the first ten letters of the alphabet?

## Homework Equations

## The Attempt at a Solution

First I assume that by anagram they mean letters arranged in any order (like as if any two lettered word had two anagrams and any three lettered word had six).

Now as far as solving the problem goes, I don't even know where to start.. I though of using factorials for the 4 distinct letters, but I'm not even sure of that.
