Ikhaliketha yetinkhokhelo te-roulette: imbuyiselo, inzuzo lehlantekile nekulahlekelwa lokulindzelekile kwelinani lelibhejwako kunoma ngukuphi kubheja.

Kufundza umphumela

Kubheja $10 ku-straight up kubuyisa $360 nakuwina (inzuzo ye-$350 kuhlanganise nelinani lelibhejwako) futsi ulahlekelwa ngu-$10 nangabe kungawini. Ngesilinganiso sekujikeleta lokunyenti loko kukulahlekelwa ngu-$0.27 ngekujikeleta, lokungu-2.70% welinani lelibhejwako.

Indlela nemicabango lesisekelo

Inkhokhelo = kubheja × (36/n − 1). Linani lelilindzelekile = p·W − (1−p)·kubheja = −kubheja/37. Ngaphandle kwe-la partage.
