Kukondera kwa Gudumu la Roulette

Gudumu la roulette lokondera limakonda tibowo tina chifukwa cha vuto lenileni: fret yomasuka, rotor yosalinganika, tibowo totha. Kukondera kwa gudumu la roulette kulipo ndipo kwapezeredwapo mwayi. Vuto n’loti gudumu lachilungamo mwangwiro limapanga “manambala otentha” nthawi zonse, choncho funso silikhala ngati nambala ili yotentha, koma ngati ndondomeko yonse ndi yopendekeka kwambiri kuposa momwe mwayi umalolera.

1. Tengani chitsanzo cha gudumu lachilungamo

Mazungulidwe otengedwa kuchokera ku gudumu loyerekezedwa lopanda kukondera konse. Sinthani kukula kwa chitsanzo ndipo yang’anani kabowo kotentha kwambiri.

Mzere uliwonse ndi kabowo motsatira dongosolo la gudumu. Mzere wa madontho ndi chiwerengero choyembekezeka, n/37. Gulu lopakidwa mthunzi ndi ±2 kupatuka kokhazikika: pa gudumu lachilungamo pafupifupi kabowo kamodzi pa makumi awiri kadzatulukira kunja kwake mwamwayi chabe.

3. Mayeso a chi-square

Mayesowa amawonjezera kutalika kumene kabowo kalikonse kali ndi zoyembekezeka, kowirikizidwa ndi kokha ndi koyezedwa. Pa gudumu lachilungamo chiwerengerochi chimatsatira kagawidwe ka chi-square ndi madigiri a ufulu 36; p-value yochepera 0.05 mwamwambo imatchedwa yofunika.

χ² = Σ (Oᵢ − Eᵢ)² / Eᵢ Eᵢ = n/37 df = 36
n = 370 · E = 10.00 · χ² = 32.80 · p = 0.622

Chenjezo la kukula kwa chitsanzoPansi pa pafupifupi mazungulidwe 1,000 mayesowa alibe pafupifupi mphamvu iliyonse yozindikira kukondera kotheka, ndipo zotsatira “zofunika” pa p < 0.05 zidzachitika mwamwayi pa 1 mwa zitsanzo 20 zachilungamo zilizonse zimene mumayang’ana. Kuyesa magudumu ambiri, kapena kuyesanso gudumu lomwelo mpaka lipambane mayeso, kumatsimikizira zotsatira zabodza.

4. Mazungulidwe angati amene mungafune

Mazungulidwe ofunika kuti muzindikire kabowo kamodzi kogunda kawirikawiri kuposa 1/37, pa mlingo wa 5% wa mbali imodzi ndi mphamvu ya 80%. Kabowo kogunda 1 pa 35 m’malo mwa 1 pa 37 kangakhale phindu lalikulu kwa wosewera, ndipo kumafuna makumi masauzande a mazungulidwe olembedwa kuti kutsimikizidwe.
