In both cases you have the same probability of winning the 20k total (15k more). In both situations you have no bankroll ror because this is a one-shot thing and you're not going to be doing it infinitely (or even at all with your original $10k bank that you started with, you're just out on a night with the guys trying to blow as little cash as possible and still be in the slots parlour with them, but you got [censored]-hot lucky, and it looks like you have a chance at your car, keep in mind that it would be nice, but not really a big deal, if you came home tonight with $5k extra, but that you've got a chance at going for the car, and you've decided to do it... how do you do it?).

So, the EV and ROR is the same with both options, yet there's still one correct answer.
