#1**+1 **

1.

For this, you'll use factorials.

So, to find the possible orders, you have to do 6!. This is the same as 6*5*4*3*2*1.

6! = 720

So, the answer is *720.*

2.

You can actually do this on the calculator as well! Use nPr(n, r). n is the number on the left side, and r is on the right.

nPr(9, 5) = 15,120

So your answer is *15,120.*

Hope this helped!
