In the battle of the bands contest, in how many ways can the four participating bands perform

There will be four different options of ways they can perform, there will be three choices of ways they can perform for the second band, two choices for ways they can perform for the third band and only one option for the first band. Therefore you would write the equation as follows: 4*3*2*1, 4*3=12, 12*2=24, 24*1=24 so therefore the answer is 24
