Ntsengo lowu Languteriweke eka Roulette

Ntsengo lowu languteriweke wa roulette i mbuyelo wa xiringaniso wa xibejo loko a wo xi phindaphinda hilaha ku nga heriki. Eka roulette ya le Yuropa wu fana eka xibejo xin'wana na xin'wana lexi tolovelekeke: u lahlekeriwa hi 1/37 ya mali ya xibejo xin'wana na xin'wana, hi xiringaniso, eka rhendzeleko rin'wana na rin'wana.

Hi marito yo olova

Ehleketa u veka xibejo lexi fanaka xa $10 eka yo tshuka minkarhi ya miliyoni. Marhendzeleko man'wana ma hlula $10, man'wana ma lahlekeriwa hi $10. Hlanganisa mbuyelo wun'wana na wun'wana kutani u avanyisa hi miliyoni: u kuma kwalomu ka −$0.27. Nomboro yoleyo i ntsengo lowu languteriweke wa xibejo xa roulette. A hi leswi humelelaka eka rhendzeleko rihi na rihi; i xiringaniso xa nkarhi wo leha eka rhendzeleko rin'wana na rin'wana.

Nhlamulo yo komaEV = nkoteko wa ku hlula × mali leyi hluriweke − nkoteko wa ku lahlekeriwa × mali leyi lahlekeke. Eka xibejo xin'wana na xin'wana lexi tolovelekeke xa roulette sweswo swi fika eka −2.70% ya mali ya xibejo.

Fomula ya EV ya xibejo xa roulette

EV = p · W − (1 − p) · S
p = n/37 · W = S·(36/n − 1) · n = tinomboro leti funengetiweke · S = mali ya xibejo

Siva nawu wa hakelo ya roulette, 36/n − 1, kutani n ya tisusa. Leyi i mhaka hinkwayo ya vuyelo bya khasino eka layini yin'we:

EV = (n/37)·S·(36/n − 1) − ((37−n)/37)·S
= S·(36 − n − 37 + n)/37
= −S/37

Ringeta: xibalo xa ntsengo lowu languteriweke wa roulette

Hlawula leswaku xibejo xi funengeta tinomboro tingani. Nkoteko na hakelo swa cinca; ntsengo lowu languteriweke a wu cinci.

Leswi swi langutekaka xiswona hi ku famba ka nkarhi

Mbuyelo wa xiringaniso eka rhendzeleko eka xibejo xa $10 eka yo tshuka, loko marhendzeleko ma ri karhi ma andza. Eku sunguleni, nkateko wu fuma; xiringaniso lexi yaka emahlweni xi tshamiseka ekusuhi na −$0.27 loko sampulu yi ri karhi yi kula. Leku i ku hlangana ka nkarhi wo leha loku khasino yi tshembeke eka kona.

Rhendzeleko hi rhendzeleko, xiringaniso lexi yaka emahlweni xi tshika ku tsekatseka kutani xi tshama ehansi nyana ka zero.

Mavonelo yo hoxeka lama tolovelekeke

“EV ya le hansi ka zero yi vula leswaku ndzi ta lahlekeriwa tisesheni hinkwato.”

E-e. Yi vula leswaku xiringaniso xa tisesheni to tala i ku lahlekeriwa. Tisesheni hi yin'we hi yin'we ti hambana swinene, ngopfu-ngopfu eka swibejo swa ku hambana-hambana lokukulu ku fana na straight up.

“Khasino yi lava nkarhi wo leha leswaku yi hlula.”

Vuyelo bya khasino byi tirha eka rhendzeleko rin'wana na rin'wana; leswi nkarhi wo leha wu swi endlaka i ku endla leswaku mbuyelo wu vhumbeka. Eka sesheni yin'we, nkateko i matimba lamakulu.

“Swibejo swin'wana swi na EV leyinene ku tlula swin'wana.”

A swi tano eka roulette ya le Yuropa, handle ka xin'we: hi nawu wa la partage kumbe wa en prison, swibejo swa mali yo ringana swi na hafu ya vuyelo bya khasino lebyi tolovelekeke.
