I got this question wrong on my test, and I have to correct it :/
How many permutations are there of all the letters in the word "TEXAS" ?
The answer to this part is 120, but I have no idea on how to solve the second part without having to write it all down.
*How many of these permutations begin with 2 consonants?

Wait... so it's 3 multiplied by 4? Sorry, I'm not used to reading when it's typed out.

3 multiplies by 4 factorial.
