Prob. of winning session?

[MickeyHoldem]

Can you calculate the probability of having a winning session of length t (in hours) given an hourly winrate & standard dev. or do you need more info?

say....
winrate = $17/hr
std. dev. = $140/hr

Using Excel function NORMDIST:

=1 - NORMDIST(0,winrate*t,std.dev.*sqrt(t),true)
