LONELY: consist from L, O, N, E & Y
That like possibility機率
First place has 4 letters to place in
Second place has 4 letter to place in also
Third place has 4 letter to place in also
Fourth place has 4 letter to place in also
So 4*4*4*4 = 256

Are you sure the answer is 192?
L(1) O(2) N(3) E(4) L(5) Y(6)
6! / (6 - 4)! =
(1 x 2 x 3 x 4 x 5 x 6) / (1 x 2) =
720 / 2 =
360
I'm a good decade removed from this classroom stuff, so I might be completely wrong.
