According to a chart provided by Lou Krieger that I have, the odds of hitting a set with a wired pair is 11.8% or equivalently, a 7.5:1 long-shot.

One way to calculate this: you need to enumerate the total number of flops (out of the 50C3 = 19,600 possible ones) that would contain one or more of your two outs.

By immediate pot odds alone, if there is >=7.5 small bets in the pot pre-flop, you should stay in to draw to your set. However, given how high the implied odds are for a set (since it's so well disguised), it's still profitable to see the flop when there are less than 7.5 small bets in the pot pre-flop.

You need to be aware of potential raises behind you (as well as check raises in front of you) that might impact your odds.
