Isibonelo: Isu lamadazini amabili ku-roulette

Uhlelo: isu le-roulette lamadazini amabili

U-$10 edazininiukubhejaIdazini1–12, 13–24 noma 25–36, kukhokha u-2:1.Funda konke → lokuqala no-$10 kwelesibili. Inombolo esuka ku-1 kuya ku-24 ikhokhela idazini elilodwa u-$20 bese kulahleka u-$10 kwelinye: +$10. Inombolo esuka ku-25 kuya ku-36, noma iqandaisondoIqandaIgodi elilodwa eliluhlaza elingambozwa ukubheja okulingana nemali, okwedazini noma okwekholamu; umthombo wenzuzo yekhasino. Kubuye kuthiwe: iqanda elilodwa, 0.Funda konke →, ilahlekisa kokubili: −$20. Inani elilindelekileizibaloInani elilindelekileUmphumela ovamile ekubhejeni ngakunye esikhathini eside. U-−1/37 wenani elibhejwayo kukho konke ukubheja okujwayelekile kwaseYurophu.Funda konke →: (24 × 10 − 13 × 20)/37 = −20/37 = −$0.54 ekujikelezeni ngakunye, okuyi-2.70% ka-$20. Izinga lokuwina ngu-64.9%, futhi yilona nani elithengisa lokhu kubheja.

Ukujikeleza 1–25

Ukuwina okuyishumi nesishiyagalombili, ukuhlulwa okuyisikhombisa: +$180 − $140 = +$40. Ukuhlulwa okuyisikhombisa kwakuhlanganisa iqanda elilodwa nochungechunge lwezinombolo ezintathu zedazini lesithathu ekujikelezeni 11–13 olwabiza u-$60 kulandelana futhi lwazwakala luyinto engavamile. Kwakuyi-35.1% ifika iqoqene ndawonye, futhi izinto ezinjalo ziyaqoqana.

Ukujikeleza 26–50

Ukuwina okuyishumi nantathu, ukuhlulwa okuyishumi nambili: +$130 − $240 = −$110. Ukuhlulwa okuyishumi nambili ekujikelezeni okungu-25 kuyinto eyenzeka ku-20% yezikhathi, akuyona into engavamile. Ekugcineni −$70; okuphezulu kakhulu +$90 ekujikelezeni 31. Lokhu kubheja akuzange kuveze ukuguquka okukhulu kunoma yiluphi uhlangothi, ngoba ukuwina ku-$10 nokuhlulwa ku-$20; kumane kwagaya kancane kancane.

Izibalo

Isamba esibhejiwe ngu-$1,000 ekujikelezeni okungu-50. Ukulahlekelwa okulindelekileizibaloUkulahlekelwa okulindelekileInani elilindelekile liphindaphindwe ngemali yonke ebhejiwe; inani elilahlekayo ngokwesilinganiso phakathi neseshini noma esikhathini esithile.Funda konke → ngu-$27; okwenzekile −$70, cishe ukuchezuka okujwayelekileizibaloUkuchezuka okujwayelekileImpande yesikwele yokuguquguquka (variance); ibanga elivamile lomphumela ukusuka enanini elilindelekile.Funda konke → okukodwa ngaphansi (σ ekujikelezeni ngakunye icishe ibe ngu-$14, ngakho cishe u-$100 ekujikelezeni okungu-50). U-$20 ofanayo kokubomvuukubhejaBomvuUkubheja okulingana nemali ezinombolweni eziyi-18 ezibomvu. NgesiFulentshi: rouge.Funda konke → ngabe waba nokulindelekile okufanayo kanye ne-σ enkulu, cishe u-$140 kuyo yonke iseshini: amadazini amabili ayindlela yokuguquguqukaizibaloUkuguquguqukaIsilinganiso sokuthi imiphumela ihlakazeke kangakanani ezungeze inani elilindelekile. Kuphezulu ku-straight up, kuphansi ekubhejeni okulingana nemali.Funda konke → okuphansi yokulahlekelwa yinani elifanayo.

Lokho okuboniswa yiseshini

Ukumboza izinombolo ezingu-24 kwenza i-roulette izwakale njengomdlalo ovamise ukuwina kuwo, futhi uyawina ngempela: ku-64.9% yokujikeleza. InkokheloimaliInkokheloLokho ukubheja okuwinile okubuyisayo, okushiwo ngokuthi “X ku-1” ngaphezu kwenani elibhejiwe elibuyiswayo.Funda konke → ihlelwe ukuze i-35.1% olahlekelwa kuyo ikubize kabili kunalokho okukhokhelwa wukuwina, futhi isilinganiso silungiswe yithebula lokubhejaokokusebenzaIthebula lokubhejaIgridi yokubheja ephrintiwe etafuleni. Kubuye kuthiwe: itafula, i-felt, indwangu.Funda konke → sibe ngu-−1/37 wenani lonke elibhejiwe. Engeza ithokheniimaliIthokheniUphawu olumele inani elinqunyiwe, olubekwa ethebuleni lokubheja ukuze ubheje. Kubuye kuthiwe: check.Funda konke → eqandeni ukuze ibe “umshwalense” futhi inzuzo yekhasino ehlanganisiwe isengu-2.70%, ngoba nomshwalense unentengo engu-2.70%. Ikhasi elithi Inkinga: Amadazini amabili nethokheni likuchaza ngokuphelele.
