Isibali sezinkokhelo ze-roulette

Isibali sezinkokhelo ze-roulette: imbuyiselo, inzuzo ehlanzekile kanye nokulahlekelwa okulindelekile kwenani elibhejwayo kunoma yikuphi ukubheja.

Ukufunda umphumela

Ukubheja u-$10 ku-straight up kubuyisa u-$360 uma kuwina (inzuzo engu-$350 kanye nenani elibhejiwe) bese ulahlekelwa ngu-$10 uma kungenjalo. Ngokwesilinganiso sokujikeleza okuningi lokho kungukulahlekelwa ngu-$0.27 ngokujikeleza ngakunye, okungu-2.70% wenani elibhejwayo.

Indlela nemicabango eyisisekelo

Inkokhelo = inani elibhejwayo × (36/n − 1). Inani elilindelekile = p·W − (1−p)·inani elibhejwayo = −inani elibhejwayo/37. Akukho La Partage.
