The answer above mine is wrong. You use permutations when the arrangement of objects have to be in a certain order. In your case, AB and BA are the considered the same, therefore, using the permutations formula will not give you the correct answer. How many ways can all the letters be grouped is your question. For this, you need to use the combination formula. If you type in “combination formula” in Google, it will give you links on how to use it. Good luck!
