Okey guys, thanks for answers, good, pretty quet difficult theme

About math, lot people says it disocvered just people, in universe, or in science the math does not appear. So if we trying to see the roulette without math, what is your opinion?

And : what is difference between positive variance and negative variance.

Is it right, that if we play more and more spins, the house edge increasingly shows, and the variance can be better handle?
