Question

Using the letters THURSDAY without replacement, how many 4-letter words end in Y?

Answer 1

like asking
" using the letters THURSDA how many 3 letter words can you make without replacement?"

Answer 2

7 P 3? but how do we do if we did that, that we couldn't just tack on the Y the
n on the first or last position?

Answer 3

because if your making these 3-letter words.. would we not be counting the possibilities if Y could be at the beginning of the word or at the last position o_O?
