Kujikeleta lokutimele ku-roulette
Kujikeleta ngakunye kucala kabusha ngalokuphelele.
Umphumela wekujikeleta kunye awunawo umtselela kulokulandzelako. Tonkhe tibalo kulelisayithi tisekelwe kulelociniso.

Kungani “kujikeleta kwe-roulette akutimele” kungemanga ngekwefiziksi

Lokulandzela kuko
Lonkhe luhlelo lwekubheja ngumsebenti wemiphumela leyendlulile. Nangabe imiphumela leyendlulile ingenalo lwati ngekujikeleta lokulandzelako, kute umsebenti lonjalo longenta ncono linani lelilindzelekiletibaloLinani lelilindzelekileUmphumela wesilinganiso ngekubheja ngakunye ngekuhamba kwesikhatsi lesidze. −1/37 yelinani lelibhejiwe kuko konkhe kubheja lokujwayelekile kwaseYurophu.Fundza konkhe → lekubheja lokulandzelako. Lena yinguculo lesemtsetfweni yemphikiswano lemelene netinhlelo, futsi ngiko emakhasi emasu angabhalwa kusengaphambi ngetinhlelo letingakasungulwa: bufakazi abuncikile emtsetfweni.
Lapho bekungeke kusebente khona
Kuphela nangabe lisondvo belichemile ngekwesakhiwo noma kuphosa kwe-croupier bekubikeleka. Leto tihloko teLilabhorethri. Ngisho nalapho, kuncika kusefiziksi, hhayi emiphumeleni leyendlulile: umgodzitinsitaUmgodziLesinye setikhala letingu-37 letinetinombolo ku-rotor.

Idatha yekujikeleta lokwendlulile beyitawuba bufakazi ngelisondvo, lokuyintfo lehlukile kuphethini emiphumeleni.
Kutimela kukucabangela
Kuphindzaphindza ematfuba kuvunyelwe kuphela nangabe tehlakalo titimele, futsi lisondvo le-roulette litfola lelo lilungelo ngefiziksi. Kuletinye tindzawo kufanele kuhlolwe. Nga-1999 Sally Clark, ummeli waseNgilandi, walahlwa licala lekubulala emadvodzana akhe lamabili labeyinsana. Dokotela webantfwana watjela ebehluleli (jury) kutsi litfuba lekufa kwetinsana letimbili tisembhedzeni (crib death) emndenini lofana nelakhe lingu-1 etigidzini letingu-73, linani lalitfola ngekuphindzaphindza ngalo ngekwalo 1 ku-8,543, litfuba lekufa kunye. Kuphindzaphindza ngalo ngekwalo kutsatsa kufa lokukabili njengekujikeleta lokukabili kwelisondvo. Kodvwa bomnakabo bahlanganyela tinhlobo telufuto nelikhaya, ngako ngemuva kwekufa kunye kwensana embhedzeni, kwesibili kunelitfuba lelikhulu kakhulu kunekwekucala. I-Royal Statistical Society yakusho loko ebaleni nga-2001, futsi kulahlwa kwa-Clark licala kwachitfwa ekudlulisweni kwesibili kwelicala nga-2003, ngemuva kwekutsi kuvele bufakazi betekwelapha lobebungakadalulwa. Hunacek (2025) usebentisa leli cala kufundzisa umtsetfo lelikhasi lelisekelwe kuwo: phindzaphindza kuphela lokutimele.
Kutimela nematafula e-RNG
Ematafula esofthiwe atsatsa umphumela ngamunye esikhicitini setinombolo letingahlelekile lesicinisekisiwe lesihlolelwa kanye lesici: kutimela kwekulandzelana etigidzini tekudvonswa. Lisondvo lelinyakatako ngumhlobiso nje. Litafula le-RNG lelingakhombisa kuncika belitawuhluleka kucinisekiswa, futsi loko kukuhlolwa lokucinile kakhulu kunanoma ngukuphi umdlali langakwenta.
Imibuto
Hhayi emgodzini.

Titudiyo tishintja indlela yekuphosa kute tikuvimbele.
Ekuhlatiyeni kuchema ekujikeleteni lokutinkhulungwane, ngekwemgomo. Ekujikeleteni lokulandzelako, cha.
Bumnandi betibalo
Zama loku ngekwakho kucala. Sixazululo ngasinye sifihliwe; sivule nawukulungele.
Kubheja lokubekwa ngaphambi kwekujikeleta lokubili kukhokha imali lelinganako nangabe inombolo yesibili inkhulu kunalekucala. Kulingana kuyalahlekelwa, futsi 0 kubalwa njengenombolo lencane kakhulu. Kubita malini elisondvweni laseYurophu?

Kujikeleta lokubili kutimele, ngako inombolo yesibili inelitfuba lelilinganako lekuba nkhulu nobe lekuba ncane kunalekucala.

Ngako kubheja kuwina ngelitfuba la-(1 − 1/37)/2 = 18/37, ncamashi litfuba lalokubovu, futsi kubita 2.70% lofanako.
Nangabe bewungakubeka ngemuva kwekubona inombolo yekucala bekutawuba sipho: ngemuva kwa-0 kuwina tikhatsi letingu-36 ku-37. Yingako kubheja lokunjena kufanele kuvalwe ngaphambi kwekujikeleta kwekucala.
