your school newspaper has an editor in chief and an assistant editor in chief. the satff of the newpaper has 12 students. in how many ways can students be chosen for these two positions?

Again the order is important here.SO it is a permutation. so total number of ways = 12P1 * 11P1

i got 132 ways

OpenStudy (anonymous):

that is correct since 12P1 = 12 and 11P1 =11.
