Need help - What's the SD for playing starting hands?

[mauisupaman]

Happy new year all. This is not a very practical question, but I am curious. If I'm playing pretty tight, say around 10% of all starting hands then I should on average play 1 hand per orbit on a ten handed table right? But what is the standard deviation for playing 1 out of 10 hands?

I ask b/c I was sitting at a table last night with a brutal run of crappy cards and was wondering what the SD for such an event was.

A hui hou,
Adam
