Question

Baby McKenna wants to arrange 10 blocks in a row. How many different arrangements can she make?

Answer 1

3,628,800

1) Note that in these arrangements, according to the text the order of the blocks does not matter.

2) When this kind of thing happens we call this is a Permutation, in which the blocks may present in any order, that is not relevant

3) We can calculate it like this:

`P_(10)=10!=10*9*8*7*6*5*4*3*2*1=3,628,800`

Thus, there are 3,628,800 different ways to arrange those 10 blocks
