Is it time to reopen: How do I calculate gambling edge using average win?

A probability theory question (here) was asked when this site was fairly new. I suspect that the closure of this question might be a result of being asked during the website's infancy -- to me, while not a masterpiece, it doesn't seem off-topic (at least when compared to today's questions).

and if not...

Could I encourage votes to re-open this question?

• The questioner does not seem to have returned soon after the closure, unfortunately. – J. M. is a poor mathematician Nov 25 '10 at 5:44
• Now that the question has been reopened, let's close this one :-) – Aryabhata Dec 5 '10 at 5:58
• @mods: a status-completed would be nice here, I think. – J. M. is a poor mathematician Dec 8 '10 at 5:02
