Hello,

i have a problem calculating this:

I have a bankroll of : 100 $

i have 65% chance to win 10$

i have 35% chance to lose 10$

and i have unlimited tries.

what is the % of my bankroll to become 0

example: first hit 65% for my bankroll to become 110$ and 35% chance for my bankroll to become 90$

thanks.
