## American roulette HA and Craps question

If an operator is running a roulette promotion that pays double on a straight up winner on the number 25, what does that do to the House Advantage?They are also running a bonus payout promotion on Craps: If the Shooter rolls a 2 and then 5 back to back they automatically win a $250 bonus. What are the odds of rolling that?

Thanks

1) So betting on 25 pays 70 to 1? If that’s what you really mean, then betting on 25 on a double zero wheel is a huge player advantage. Betting $1 returns $1.86842.

2) There are a few ways to think about this dice problem, but I’ll assume you meant what is the probability that the next two throws are a 2 then 5. That’s 0.3086%.

for the Craps, if you bet the next throws are 2 and then 5, I get probability of 0.0061728395061728, so I differ from Unjon, one of us is wrong.

If I am right, it's 1 chance in 162, and a fair bet would be 161:1

250 to one you should definitely pounce on in a regular casino. I have to say this seems like screwy stuff to me, I suspect it is an online casino, if so I would check it out very thoroughly before betting.

I can't edit, just realized that it might be $250 to some other figure. Is it an online casino?

The chance the next roll is a 2 is 1/36. The chance the following roll is a 5 is 4/36. The combined chance is 1/36 * 4/36 = 4 / 1296 = 0.3086%.

Odious, did I mess up somewhere?

Unjon, you were correct , I was using 1/18 * 1/9 for some dumb reason. 1 chance in 324 assuming you guessed at the bet right [we didn't get an answer] . 250 to one wouldn't cut it

our boy has flown the coop in the meantime? I still think it was online casino betting. I hate to answer something only to find out that it is some fly-by night outfit that never pays , that it is theoretically +EV becoming a mute point
