Umcuphi wokuthambekela kwevili
Irekhodi yemijikelo engama-3,000 evilini elinokuthi lithambekile okanye lingathambekanga. Sebenzisa izixhobo zeLebhu ukufumana icandelo elishushu, okanye uvakalise ukuba ivili lilungile.
Amavili amahlanu, izigqibo ezintlanu. Imephu yobushushu, igrafu yemivalo enebhanti le-±2σ kunye novavanyo lwe-chi-squareilebhuUvavanyo lwe-chi-squareUvavanyo lwezibalo-manani oluthelekisa ukuphuma okubonwayo kwisikhewu ngasinye nokulindelekileyo u-n/37. Lusetyenziselwa ukugweba ukuba ivili lithambekile na.Funda yonke → zisetafileni; ukuskena amacandelo kuyafumaneka njengencam, kodwa kukubiza inqaku elinye. Elinye lamavili lilungile.

Amanqaku
9–10: uJagger ngewayefuna ubukele ivili.
6–8: uyakwazi ukufunda imephu yobushushu nokungakholwa sisiphumo esibonakala ngathi siyinyani kodwa singesiso.
3–5: uwafumene lawo aqinileyo; ukuthambekela okuncinane nevili elilungileyo luvavanyo lokwenyani.
Ngaphantsi kwe-3: funda amaphepha athi Indlela yokufumanisa ukuthambekela kwevili le-roulette nathi Ubungakanani besampulu. Imijikelo engamawaka amathathu ayanele kancinci nje ukuthambekela okuqinileyo, kwaye ayaneli kokuncinane.
Into eyenza kube nzima
Kwivili elilungileyo elinemijikelo engama-3,000, inani elilindelekileyo kwisikhewuizixhoboIsikhewuEsinye sezikhewu ezingama-37 ezinamanani kwirotha. Kwakhona: slot, cup.Funda yonke → ngasinye ngama-81 kwaye ukutenxa okuqhelekileyo (standard deviation)izibaloUkutenxa okuqhelekileyo (standard deviation)Ingcambu yesikwere yokwahluka; umgama oqhelekileyo wesiphumo ukusuka kwixabiso elilindelekileyo.Funda yonke → kumalunga ne-9, ngoko izikhewu ezimbalwa ziya kuhlala ngaphandle kwebhanti le-±2σ ngethamsanqa nje. Isikhewu esithambekileyo esine-+40% sihlala malunga ne-113, malunga ne-3.5σ; kwi-+20% simalunga ne-97, ngaphantsi kwe-2σ, kwaye asibonakali xa sisodwa. AmacandeloiviliIcandeloIsiqwenga esiqhubekayo sezikhewu evilini, esahlukileyo kwiqela elikwibhodi yokubheja.Funda yonke → ayadibana: ukuskena izikhewu ezi-5 yindlela abadlali bokuthambekela bokwenyani ababefumana ngayo amavili, kuba izikhewu ezingabamelwane zabelana ngempazamo yoomatshini.
Imibuzo
Kuba obona buchule bunzima ekudlaleni ngokuthambekela asikokufumana icandelo elishushu; kukungafumani elingekhoyo.
Amawaka ukuze kufumaneke ukuthambekela okuqinileyo; amashumi amawaka okuncinane. Usapho lukaJagger lwabukela amavili iiveki ngeeveki.
Uncumo
Fumana icandelo. Okanye uvume ukuba alikho.
