Suppose a Standard Brownian Motion Wt without drift.
Wt stops when any of the three circumstances below occurs:
Wt=b>0
Wt=a<0
t=T
Traditional Gambler's Ruin problem focuses only on the T=inf case.
However, I want to know P(W ends up at b)
and P(W ends up at a)
and of course P(W ends at T)
If you could solve Xt=Wt+ut instead in the same unfinished gambler's ruin problem.
I will give you addtional 100 points!
