Simply Risk of Ruin Question

[Nottom]

Suppose I like to play -EV games and go to a casino to play some Roulette (double zero).

If I take $50 and decide to stay until I double up or go broke what are the odds that I walk away with $100 assuming I play the following ways:
a) always bet $10 on black
b) always bet $1 on black
c) always bet $10 on the first row of 12
d) always bet $1 on 00

Even if you don't want to do the math, how would you go about finding these results?
