Mahuʻinga ʻAmanekina ʻi he Lulēti
Ko e mahuʻinga ʻamanekina ʻi he lulēti ko e ola ʻavalisi ia ʻo ha peti kapau ʻe lava ke ke toe fai ia ʻo taʻengata. ʻI he lulēti ʻIulope ʻoku tatau ia ki he peti angamaheni kotoa: ʻoku ke mole ʻa e 1/37 ʻo e peti taki taha, ʻi he ʻavalisi, ʻi he vilo taki taha.
ʻI he lea faingofua
Fakakaukau atu ki hoʻo tuku ʻa e peti tatau ʻo e $10 ki he kulokula ʻo tuʻo miliona. ʻOku ikuna ʻa e $10 ʻi he ngaahi vilo ʻe niʻihi, pea mole ʻa e $10 ʻi he niʻihi. Tānaki ʻa e ola kotoa pea vahe ki he miliona: ʻoku ke maʻu ai ʻa e meimei −$0.27. Ko e fika ko ia ko e mahuʻinga ʻamanekina ʻo ha peti lulēti. ʻOku ʻikai ko e meʻa ia ʻoku hoko ʻi ha vilo pē ʻe taha; ko e ʻavalisi ia ʻi he vilo taki taha ʻi he taimi lōloa.
Ko e fomula ʻo e EV ʻo ha peti lulēti
p = n/37 · W = S·(36/n − 1) · n = ngaahi fika ʻoku kapui · S = lahi ʻo e peti
Fetongi ʻaki ʻa e lao ʻo e totongi ʻi he lulēti, 36/n − 1, pea ʻoku tāmateʻi ʻa e n. Ko e talanoa kakato ia ʻo e tuʻunga lelei ʻo e kasino ʻi ha laine ʻe taha:
= S·(36 − n − 37 + n)/37
= −S/37
Feinga: ko ha meʻa fika ki he mahuʻinga ʻamanekina ʻi he lulēti
Fili pe ko e fika ʻe fiha ʻoku kapui ʻe he peti. ʻOku liliu ʻa e ngalingali mo e totongi; ʻoku ʻikai liliu ʻa e mahuʻinga ʻamanekina.
Hono fōtunga ʻi he faai ʻa e taimi
Ola ʻavalisi ʻi he vilo taki taha ki ha peti kulokula ʻo e $10, ʻi he tupulaki ʻa e ngaahi vilo. ʻI he kamataʻanga, ʻoku puleʻi ʻe he monūʻia; ʻoku nofo ʻa e ʻavalisi ʻoku lele ʻo ofi ki he −$0.27 ʻi he tupu ʻa e sīpinga. Ko e fakaofi ia ʻi he taimi lōloa ʻoku falala ki ai ʻa e kasino.
Ngaahi fakakaukau hala angamaheni
Meʻa fakaoli
ʻIkai ko e meʻa ʻoku hoko ʻi ha vilo ʻe taha. Ko e ʻavalisi ʻo kinautolu kotoa.
