Isibali somngcipheko wokuphelelwa yimali

Amathuba okufikelela kwinjongo yenzuzo ngaphambi kokuphelelwa yimali yokudlala, ubheja ngokulinganayo kwimali elinganayo.

Ukufunda isiphumo

Ubheja i-$10 ngexesha, unethuba le-24.6% lokuguqula i-$500 ibe yi-$750 ngaphambi kokuphelelwa yimali. Iibheji ezinkulu ziphakamisa loo mathuba kuba imijikelo embalwa ithetha iirhafu ezimbalwa ze-2.70%; zikwenza nohambo lube nesiphithiphithi ngakumbi. Zama iibheji ze-$100 ngokuchasene neebheji ze-$5 ukuze ubone umahluko.

Indlela neengcinga esisekelwe kuzo

Ukuphelelwa yimali komngcakazi (gambler’s ruin) apho p = 18/37: P(injongo) = (1 − (q/p)ᵃ)/(1 − (q/p)ᵃ⁺ᵇ), a = imali yokudlala/ibheji, b = injongo/ibheji. Ubude obulindelekileyo a/(q−p) − (a+b)·P/(q−p). Iibheji ezilinganayo zemali elinganayo kuphela.
