Odds of making nut low with A2?

[Go Blue]

I did a search but couldn't find this anywhere, even though I'm sure it's somewhere. My question is: what are the odds of making a low with JUST an A2 in your hand (nut low only)? In other words, by the river, what percent of the time will there be 3 differently ranked cards on the board lower than 9, none of which are an A or a 2. I think knowing this would at least somewhat help my game out. Thanks in advance. [img]/images/graemlins/spade.gif[/img]
