Ukulahlekelwa okulindelekile
Inani elilindelekile liphindaphindwe ngemali ephelele oyibhejayo: izindleko zeseshini ngokwesilinganiso.
Ukulahlekelwa okulindelekile = imali ephelele ebhejiwe × 1/37. Inani elibhejwayo u-$10, ukujikeleza okungu-100: u-$1,000 ubhejiwe, u-$27 ukulahlekelwa okulindelekile. Ukwenyuswa kwenani kubheja kakhulu, ngakho kulahlekelwa kakhulu.
Imali ephelele ebhejiwe, hhayi imali yokubheja

Ifomula
E[ukulahlekelwa] = Σ amanani abhejwayo / 37. Kobheja ngenani elingaguquki lokho kuyi: inani elibhejwayo × ukujikeleza / 37. Ekwenyusweni kwenaniisuUkwenyuswa kwenaniNoma yimuphi umthetho oshintsha inani elibhejwayo ngokusekelwe emiphumeleni yangaphambili. Ukwenyuswa kwenani ngemuva kokuhlulwa kulikhuphula ngemuva kokulahlekelwa, ukwenyuswa kwenani ngemuva kokuwina kulikhuphula ngemuva kokuwina.Funda konke → kuyi: inani elibhejwayo elimaphakathi × ukujikeleza / 37, futhi inani elibhejwayo elimaphakathi liphezulu kunelisisekelo, ngoba amanani abhejwayo ayenyuka ngezikhathi zokuhlulwa okulandelanayo. I-MartingaleisuMartingaleUkwenyuswa kwenani okuphinda kabili inani elibhejwayo ngemuva kokuhlulwa ngakunye. Bheka isigaba esithi “Amasu okubheja ku-roulette” ukuze ubone ukuthi kwenzani nokuthi yini engakwenzi.Funda konke → kusukela ku-$10 oyisisekelo emkhawulweni ka-$500 inesilinganiso esicishe sibe ngu-$28 ekujikelezeni ngakunye eseshini ende, ngakho ilahlekelwa cishe izikhathi ezintathu ukwedlula ukubheja u-$10 ngenani elingaguquki, ngaphandle kokushintsha amathuba anoma yikuphi ukubheja ngakunye.
Ijubane
Amatafula abukhoma ajikeleza izikhathi ezingu-40–60 ngehora, amahholo amakhasino ezingu-30–50, amatafula esivinini ezingu-90 noma ngaphezulu, amatafula e-RNG ngokushesha njengoba uchofoza. Ngenani elibhejwayo elifanayo, ijubane yilona elinomthelela omkhulu kunakho konke ekulahlekelweni okulindelekile ngehora: ukusuka etafuleni elihamba kancane ehholo uye etafuleni le-RNG elidlalwa ngokujikeleza okungu-200 ngehora kuphindaphinda kane izindleko zobusuku ngaphandle koshintsho emathubeni.
Ngonyaka
Umdlali ojwayelekile odlala amahora amabili ngesonto ngo-$10 etafuleni elibukhoma lokujikeleza okungu-50 ubheja ngokuphelele u-$52,000 ngonyaka futhi ukhokha cishe u-$1,400 wokulahlekelwa okulindelekile esondweni laseYurophu, u-$700 kwelaseFrance, u-$2,700 kwelaseMelika. Izibalo ziyadina kodwa isiphetho asidini: ukukhetha isondo netafula kubaluleke kakhulu kunanoma yiluphi uhlelo ngokuphindwe ngokungapheli, ngoba inani lezinhlelo liyiqandaisondoIqandaIgodi elilodwa eliluhlaza elingambozwa ukubheja okulingana nemali, okwedazini noma okwekholamu; umthombo wenzuzo yekhasino.

Umdlalo obaluleke ngaphezu kwanoma yiliphi ibhange
Umdlalo we-St. Petersburg, owabekwa ngu-Nicolaus Bernoulli ngo-1713, uphonsa uhlamvu lwemali luze luwele ngekhanda bese ukhokha u-$2 uma lokho kuthatha ukuphonsa okukodwa, u-$4 uma kuthatha okubili, u-$8 uma kuthatha okuthathu, kuphindwa kabili isikhathi ngasinye.

Alikho ibhange elingakhokha imiklomelo engapheli, futhi uma imiklomelo inqunyelwe kulokho ibhange elinakho, inani liyawa: ngebhange lika-$1 isigidi umdlalo ubaluleke cishe ngo-$21, nge-$1 inkulungwane yezigidi cishe ngo-$31. I-Martingale ingumdlalo ofanayo obonwa ngakolunye uhlangothi. Iwina iyunithiimaliIyunithiInani elibhejwayo eliyisisekelo uhlelo noma umdlali asebenza ngalo. Ukwenyuswa kwenani kuchazwa ngamayunithi ukuze kusebenze kunoma yiliphi itafula.Funda konke → elilodwa cishe kuyo yonke imijikelezo yohlelo futhi ilahlekelwe yikho konke ochungechungeni olude olungavamile; ngaphandle komkhawulo uchungechunge olude belungakhokhelwa ngokuwina okukhulu ngokuqhubekayo, kodwa uma kunomkhawulo alukhokhelwa, yingakho umkhawulo wetafulaitafulaUmkhawulo wetafulaInani elincane nelikhulu kakhulu lokubheja elivunyelwe.

Ukulahlekelwa okulindelekile akuwona umphumela
Noma yiphi iseshini eyodwa izohluka ekulahlekelweni kwayo okulindelekile, kaningi ngaphezu kokulahlekelwa okulindelekile uqobo.
