再睇下紅色區域﹕
$1.0=3271.85/50320*回報=$15.4
即係如果你想中紅色區域嘅獎品,除非回報比你嗰件獎品價值高過$15.4, 否則呢隻遊戲係玩唔過;
*要留意嘅係,假設簡化咗中紅色區域個概率係1/15, 但並不等於你掟15次就保證你可以中一次。可以用一個網上probability calculator裡面嘅"probability of a series of independent events", 响Event A輸入probability: 1/15=0.66667; repeat times=15, event b可ignore, 然後按calculate, 可以見到probability of A NOT occuring即係掟15次一次都唔中嘅概率係有35.5%
