Stupid Question that Shows How Bad I Suck at Math

[fimbulwinter]

took AP stats 5 years ago, should know this but don't.

If my winrate per hour is $X/hr
and my SD/hour is $Y/hr

what is the formula for % of sessions lasting N hours above $0/hr (winning N-hour sessions?)
what about above Z/hr over N hours? where Z is some arbitrary hourly winrate?

this was like chapter one of stats, i know. I work with things like animals and people which always act one way and never involve any variance or require any statistical analysis. so obviously i don't need to know this normally...

flame away.
