If there are 12 candidates in a city election. The winner will be the mayor and the runner up will be the vice mayor. How many different combinations of mayor and vice-mayor are possible?
Would it be 12P2 = 132 ? o:
The major position can be filled in 12 ways, then the v-m spot can be filled in 11 ways, so
12(11) = 132
