最近在BGA學到這款遊戲...
不過戰績不太好XD
所以就寫了一個小程式去跑看看
主要算的是當三個數字(2~12)都選定後
可以連續成功擲中此任意三個數字的次數期望值
開發語言是PHP,跑了10000次
亂數種子用系統時間:
list($usec, $sec) = explode(' ', microtime());
return (float) $sec + ((float) $usec * 100000);
以下是數據 請慢用xd

================================================
剛剛多算了標準差,大約是平均值再加上0~0.5之間的小數
如果假設為常態分布的話
以 ( 5 , 7 , 8 ): 10.3335 為例
成功連續擲出10次的機率約為50%
成功連續擲出5次的機率約為67%
成功連續擲出2~3次的機率約為75%
================================================
參考看看囉~~
有錯請指教~~(只學過皮毛統計xd)
