Answer:
B
Explanation:
There are 5 spots to fill with the digits 7, 3, 6, 1, and 2 to make a code
Think how many ways you can fill each of the spots.
spot 1: either 7, 3, 6, 1, or 2 so there are 5 ways to fill that first spot
spot 2: is can be filled in 4 ways because is given that each of the digits have to be in the code so if we used one of the numbers for the first spot now we have 4 numbers left to use
spot 3: 3 ways , spot2: 2 ways, and spot1: 1 way
The different possibilities for Sharon's ZIP Code are given by the multiplication of the numbers of ways you can fill each spot in the code 5*4*3*2*1 = 120
