Tahnk you! Found 2 solutions by Edwin McCravy, ikleyn:Answer by Edwin McCravy(20060) (Show Source):
If it were
IRritaTion
where we could tell the difference between the 3 I's and the 2 T's,
it would be 10! but since we can't, we must divide through by the
number of ways the 3 I's and the 2 T's can be arranged in each
permutation, so we divide it by 3! and 2!
