Umseshi wokuchema kwesondo
Irekhodi lokujikeleza okungu-3,000 kwesondo okungenzeka lichemile noma lingachemile. Sebenzisa amathuluzi e-“Ilabhorethri ye-roulette” ukuze uthole isigaba esishisayo, noma umemezele ukuthi isondo lilungile.
Amasondo amahlanu, izinqumo ezinhlanu. Kunebalazwe lokushisa, ishadi lemigoqo elinebhande le-±2σ kanye nokuhlolwa kwe-chi-squareilebhuUkuhlolwa kwe-chi-squareUkuhlolwa kwezibalo okuqhathanisa inani lokuwela igodi ngalinye okubonwe nelilindelekile elingu-n/37. Kusetshenziselwa ukunquma ukuthi isondo lichemile yini.Funda konke →; ukuskena izigaba kutholakala njengesiqondiso, kodwa kukulahlekisela iphuzu elilodwa. Elinye lamasondo lilungile.

Amaphuzu
9–10: u-Jagger ubengafuna ukuthi wena ubuke isondo.
6–8: uyakwazi ukufunda ibalazwe lokushisa futhi awukhohliswa umphumela ongelona iqiniso.
3–5: uthole ukuchema okuqinile; ukuchema okuncane nesondo elilungile yikho okuhlola ikhono lakho.
Ngaphansi kuka-3: funda “Indlela yokuthola ukuchema kwesondo le-roulette” kanye nelithi “Ubukhulu besampula”. Ukujikeleza okuyizinkulungwane ezintathu kwanele kancane ukuthola ukuchema okuqinile, futhi akwanele ukuthola okuncane.
Yini eyenza kube nzima
Esondweni elilungile elijikelezwe izikhathi ezingu-3,000, inani elilindelekile egodiniokokusebenzaIgodiEsinye sezikhala ezingu-37 ezinezinombolo ku-rotor. Kubuye kuthiwe: slot, cup.Funda konke → ngalinye lingu-81 futhi ukuchezuka okujwayelekileizibaloUkuchezuka okujwayelekileImpande yesikwele yokuguquguquka (variance); ibanga elivamile lomphumela ukusuka enanini elilindelekile.Funda konke → kucishe kube ngu-9, ngakho amagodi ambalwa azoba ngaphandle kwebhande le-±2σ ngenxa yenhlanhla nje. Igodi elichemile elingu-+40% liba cishe ku-113, okungaba ngu-3.5σ; ku-+20% liba cishe ku-97, ngaphansi kuka-2σ, futhi alibonakali egodini elilodwa. IzigabaisondoIsigabaIngxenye eqhubekayo yamagodi alandelanayo esondweni, ehlukile eqenjini lezinombolo ethebuleni lokubheja.Funda konke → ziyahlangana: ukuskena amagodi ama-5 yindlela abadlali bokuchema bangempela abawathola ngayo amasondo, ngoba amagodi angomakhelwane abelana ngephutha elifanayo lomshini.
Imibuzo
Ngoba ikhono elinzima kakhulu ekudlaleni ngokuchema akukhona ukuthola isigaba esishisayo; kuwukungatholi isigaba esingekho.
Izinkulungwane ukuze uthole ukuchema okuqinile; amashumi ezinkulungwane ukuze uthole okuncane. Umndeni ka-Jagger wawabuka amasondo amasonto amaningi.
Okokuhlekisa
Thola isigaba. Noma uvume ukuthi asikho.
