Pre-Flop Odds of At Least One Person Having a Pair

[cgrohman]

I know that the pre-flop odds of anyone person having a pair is 1/17= 1*(3/51). I would like to know what the chance of at least one person having a pair at a 9 person table is and how to figure this calculation out. It is not as simple as 9/17 is it?? Thanks
