Let me explain myself. In the roulette game, you can bet on dozens, that means, betting to 12 numbers which are placed separately along the wheel. (12 out of 37 total numbers). But I had this curious doubt. if you bet on a sector of the roulette, composed by 12 numbers.... the likelihood is really the same as before? I know that I'd still be 12/37, but from my point of view, it is easier to obtain that sector as the outcome as it is, physically, a part/section of the roulette. Let's say we want to do a Martingale (increasing the wager each time that we fail) Wouldn't it be easier for a dozen than for a sector to be more many times without turning out? Because on a dozen, if it will turn out or not, basically depends on randomness; amount of rebound and so on. But on a sector, it depends in more general physical factors. Thanks for your opinions!
