Ukufunda isiphumo

Ukubheja i-$10 kwibheji yenani elinye kubuyisa i-$360 xa iphumelela (inzuzo ye-$350 kunye nebheji) kwaye ulahlekelwa yi-$10 kungenjalo. Ngomndilili kwimijikelo emininzi leyo yilahleko ye-$0.27 ngomjikelo, eyi-2.70% yebheji.

Indlela neengcinga esisekelwe kuzo

Intlawulo = ibheji × (36/n − 1). Ixabiso elilindelekileyo = p·W − (1−p)·ibheji = −ibheji/37. Akukho la partage.
