Amathuba ku-roulette
Wonke amathuba e-roulette ayinani lamagodi elihlukaniswe ngo-37.
p = izinombolo ezimbozwayo / 37. Inombolo eyodwa: 2.70%. Eziyishumi nesishiyagalombili: 48.65%. Amathuba okulandelana okuthile ayatholakala ngokuphindaphinda amathuba okujikeleza ngakunye.
Ukujikeleza okukodwa
Ngalinye kwa-amagodiokokusebenzaIgodiEsinye sezikhala ezingu-37 ezinezinombolo ku-rotor. Kubuye kuthiwe: slot, cup.Funda konke → angu-37 linamathuba alinganayo, ngakho amathuba okuwina e-roulette ekujikelezeni okukodwa ayindaba yokubala nje. Ukubheja ezinombolweni ezine kuwina izikhathi ezingu-4/37, cishe u-10.8%. Akukho okunye kumathubaizibaloAmathubaIthuba lomphumela, kusukela ku-0 kuya ku-1 noma ku-0% kuya ku-100%. Inombolo eyodwa: 1/37 = 2.70%.Funda konke → okujikeleza okukodwa ngaphandle kwalokho, yingakho wonke umdlalo ungahlaziywa ephepheni elincane.
Ukujikeleza okuningana
Ukujikeleza ngakunye kuzimele, ngakho amathuba okulandelana ayaphindaphindwa. Ezimbili ezibomvuukubhejaBomvuUkubheja okulingana nemali ezinombolweni eziyi-18 ezibomvu. NgesiFulentshi: rouge.Funda konke → zilandelana: (18/37)² = 23.7%. Ebomvu bese kuba iqandaisondoIqandaIgodi elilodwa eliluhlaza elingambozwa ukubheja okulingana nemali, okwedazini noma okwekholamu; umthombo wenzuzo yekhasino. Kubuye kuthiwe: iqanda elilodwa, 0.Funda konke →: (18/37)(1/37) = 1.3%. Ishumi nesikhombisa kabili ngokulandelana: (1/37)² = 0.073%, cishe kanye ku-1,369. Ukulandelana kubalulekile ekulandelaneni okuthile kodwa hhayi ekubaleni: “ebomvu bese kuba emnyamaukubhejaMnyamaUkubheja okulingana nemali ezinombolweni ezimnyama eziyi-18. NgesiFulentshi: noir.Funda konke →” ingu-25.0%, kodwa “ebomvu eyodwa nemnyama eyodwa ekujikelezeni okubili, noma ngabe yikuphi ukulandelana” ingu-50.0%.
Okungenani kanye
Sebenzisa okuphambene. Amathuba okuthi i-straight upukubhejaI-straight upInombolo eyodwa, kukhokha u-35:1.Funda konke → ingaphumi nakanye ekujikelezeni okungu-37 angu-(36/37)³⁷ = 36.3%, ngakho amathuba okuthi iphume okungenani kanye angu-63.7%, hhayi “ukuqiniseka” abadlali abaningi abakulindele emathubeni angu-37 ka-1 ku-37. Lesi sibalo esifanayo sithi inombolo inamathuba acishe abe ngu-1 ku-3 okungaveli nhlobo ekujikelezeni okungu-37, yingakho ibhodi lemiphumela lihlale likhombisa izinombolo ezimbalwa “ezibandayo”.
Isikhathi esilindelekile sokulinda
Ngokwesilinganiso inombolo ye-straight up ivela kanye ekujikelezeni okungu-37, kodwa ukulinda kuguquguquka kakhulu: ukulinda okuphakathi kucishe kube ukujikeleza okungu-25 (ngesigamu sezikhathi ivela ngaphambi kwalokho) futhi ukulinda okukodwa kokungamashumi amabili kudlula ukujikeleza okungu-110. Izikhathi zokulinda kunqubo ye-geometric zinomsila omude, futhi umdlali “owaziyo” ukuthi inombolo isifike isikhathi sayo ngemuva kokujikeleza okungu-60 uchaza into eyenzeka kanye ezikhathini ezinhlanu.
Amaphutha ajwayelekile
Ukuhlanganisa amathuba ezenzakalo ezingenzeka zombili (ebomvu noma engalingani akuyona i-36/37; kuyi-26/37, ngoba izinombolo eziyishumi ziyikho kokubili). Ukuphindaphinda ezenzakalweni zokujikeleza okufanayo (ebomvu futhi engalingani ekujikelezeni okukodwa kuyi-10/37, hhayi u-18/37 × 18/37). Ukuthatha ukujikeleza okudlule njengengxenye yokulandelana obheja kukho manje: ngemuva kwezibomvu eziyishumi, amathuba eyeshumi nanye angu-18/37, hhayi u-(18/37)¹¹.
Ziyini izilinganiso (odds) ku-roulette, futhi zehluke kanjani kumathuba?
Amakhasino abeka izinkokheloimaliInkokheloLokho ukubheja okuwinile okubuyisayo, okushiwo ngokuthi “X ku-1” ngaphezu kwenani elibhejiwe elibuyiswayo.Funda konke → njengezilinganiso (odds). Inombolo eyodwa iwina ngamathuba angu-1/37, ngakho izilinganiso zokuwina e-roulette enombolweni eyodwa zingu-36 ku-1 ngokumelene nawe. Inkokhelo engu-35 ku-1 ngakho-ke isilele iyunithiimaliIyunithiInani elibhejwayo eliyisisekelo uhlelo noma umdlali asebenza ngalo. Ukwenyuswa kwenani kuchazwa ngamayunithi ukuze kusebenze kunoma yiliphi itafula.Funda konke → elilodwa, futhi lokho kuyinzuzo yekhasinoizibaloInzuzo yekhasinoIngxenye yenani ngalinye elibhejwayo ikhasino eyigcinayo ngokwesilinganiso: ama-2.70% ku-roulette yaseYurophu.Funda konke → ngesimo sayo sokuqala. Ukuguqula: izilinganiso ngokumelene = (1 − p)/p; amathuba = 1/(izilinganiso + 1).
Ifomula
Imibuzo
(1/37)² = 1/1369 ≈ 0.073%.
36/37 = 97.3%. Iqanda yilokho okusele.
Zonke ezingu-37 zingu-1/37. Ishumi nesikhombisa yinombolo ebhejwa kakhulu, futhi lokho kuyiqiniso ngabantu.
Ubumnandi bezibalo
Zama lezi ngokwakho kuqala. Isixazululo ngasinye sifihliwe; sivule uma usukulungile.
Ubheja ku-bomvuukubhejaBomvuUkubheja okulingana nemali ezinombolweni eziyi-18 ezibomvu. NgesiFulentshi: rouge.Funda konke →, ukujikeleza emva kokujikeleza. Ayini amathuba okuthi ukuwina kwakho kwesihlanu kufike ncamashi ekujikelezeni kwesishiyagalombili? Futhi ukuthi ube nokuwina okuhlanu ekujikelezeni okuyisishiyagalombili kokuqala?
Bonisa isixazululo
Impendulo 12.9%, cishe 1 ku-8, ukuze ukuwina kwesihlanu kufike ekujikelezeni kwesishiyagalombili. 33.4% wokuwina okuhlanu ngaleso sikhathi.
Ukuwina kwesihlanu ekujikelezeni kwesishiyagalombili kusho izinto ezimbili: ukujikeleza kwesishiyagalombili kuyawina, futhi ukujikeleza okuyisikhombisa kokuqala kuqukethe ncamashi ukuwina okune nokuhlulwa okuthathu, nganoma yiluphi uhlelo. Kunezindlela ezingu-35 zokubeka ukuwina okune ekujikelezeni okuyisikhombisa.
Ngakho amathuba angu-35 × (18/37)⁵ × (19/37)³ = 35 × 0.02725 × 0.1354 = 12.9%.
Ukuze uthole ukuwina okuhlanu ngokujikeleza kwesishiyagalombili, engeza amathuba afanayo okuwina kwesihlanu ekujikelezeni kwesihlanu, kwesithupha nokwesikhombisa: 2.7% + 7.0% + 10.8% + 12.9% = 33.4%. Izazi zezibalo zikubiza ngokuthi ukusabalala kwe-negative binomial: ukuthi kuthatha imizamo emingaki ukuthola inani elinqunyiwe lokuphumelela. U-Taylor (2021) uxazulula umbuzo ofanayo esondweni laseMelika, 12.2%.
Okokuhlekisa
Bala amagodi. Hlukanisa ngo-37. Phindaphinda uma kulandelana. Kuphelile.
