Ah...I see. I am not much of a gambler either, so this is a very useful piece to know why Roulette gambling, in the long run, turns negative for the gambler. Thank you.
I do not have a lot of background on statistics. Hoping someone here could explain why in Roulette game, although the apparent chances of getting number between 0-18 (inclusive) and 19-36 (inclusive) are the same, we lose money if we keep playing more and more numbers of games.
As an immigrant with no family to rely on in the US, I always give credit to Reddit for helping me learn so many things from buying old/used car, applying to grad school, to looking for an apartment. Just like you said, its diverse user base means it has almost all the information one needs. I hope it never changes (although with the recent re-design, I'm afraid it might have unintended repercussions...)
