>>12800002They're different distributions. The first one is a Bernoulli distribution, the second one is a binomial one. With sample size this large you can approximate the latter with the normal distribution
>Which one gives the casino the higher edge?For the first one, the odds are 18/38 (assuming double zero is a thing) giving the mean payout of 4736$ and the variance is 0.25.
For the second one, the mean is 4736$ as well, but the variance is 2493$
Basically, the "edge" is the same for both, but results vary way more significantly each time this is done in the second case.
