Question 262660
The basic format is this:


Number of permutations = # of choices for first slot * # of choices for second slot * # of choices for third slot * # of choices for fourth slot * # of choices for fifth slot



Since we have 5 choices for the first position, 4 for the second (since 1 computer can't take up two spots), 3 for the third, 2 for the fourth, and 1 for the fifth, we get


Number of permutations = 5*4*3*2*1 = 120



So there are 120 different permutations. 



You can choose to use the permutation formula, but you'll basically use this idea.
