Imashini Iharura Amahera yo Gukinisha Ruleti

Igiharuro c'amahera yo gukinisha ruleti kikwereka ivyo ingengo y'amahera itwara ku isaha ku mahera y'itego n'umuvuduko runaka, n'igihe isanzwe imara.

Ugusoma ivyavuyemwo

Ku $10 ku kuzunguruka kumwe no 50 inzunguruka ku isaha utega $500 ku isaha kandi ukabura $13,51 muri ayo ku mpuzandengo. Ihindagurika ry'isaha ku yindi (±$70,71) riruta cane igihombo citezwe; ni co gituma ibihe vyo gukina vyumvikana nk'impfindo, mu gihe imyaka itameze gutyo. “Amasaha ku rugero rwitezwe” ni impuzandengo; isaha mbi ishobora gutwara kimwe ca gatatu c'amahera yo gukinisha angana na $500.

Uburyo n'ivyiyumviro

Amatego ya rimwe kuri rimwe. Igihombo citezwe = amahera y'itego × inzunguruka / 37. Ihindagurika = amahera y'itego × √inzunguruka (σ ≈ 1 ku gice ku matego ya rimwe kuri rimwe).
