ok, lets say there is a 3 number lottery drawing. there are 36 possible numbers to be picked. after a number is picked, it can not come up again. how many different outcomes are possible?

36*35*34 = 42840. I think.

 

[Vincent]

36!/33!/3!

If order matters...36*35*34=42840
If order doesn't matter(abc=acb=bca=...) 42840/3! = 7140
