hi betsy !
this is pretty basic, and has to do with PERMUTATIONS.
let's solve without going into technicalities (which you may be taught in class)
q1
there are 4 choices for the 1st letter,
3 choices for the 2nd letter,
2 choices for the 3rd letter
and only 1 choice left for the 4th letter.
multiply all to get 4 x 3 x 2 x 1
= 24 arrangements
-----------------------------
q2
similarly,
3 x 2 x 1
= 6
-----
q3
similarly,
5 x 4 x 3 x 2 x 1
= 120
--------
