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!
