The letters of the word star are written on individual cards. if you always choose three cards and then put them back before the next set of three cards, how many different permutations will you have?
list all the different permutations in the space provided

Ok so here is the explanation:   when you pick the first card, you have 4 possibilities.
for the second, you have 3 possibilities.
for the third, you have 2 possibilities.
so what we do is:
4*3*2 = 24
there are 24 ways to arrange the 3 cards drawn from 4 
hope this can
