Best ResponseYou've already chosen the best response.0Hey there! We can simply use factorials to figure this out! Let's do this!!! There are 5 letters, so the number of combination would be 5! but wait, there are 2 A's, and they can be interchanged and still would be the same, so we have to divide by 2!\[\frac{ 5! }{ 2! }=60\]
