, b  u- \. ~7 k) q- e现代的老虎機都是基于一种被称为随机数生成器的技术来计算结果。老虎機的返奖率通过编程来实现一个不低于法定返奖率的数值。通常有专门的博彩会员会来决定了最低的返奖率是多少。* x! }: \4 G, h 
如果一台老虎機宣传它的返奖率是 99%, 说明 1% 的总投注额将成为这台老虎機的利润。那么是否意味着每次玩家投入100块,都会拿到 99 块呢?那么什么是随机数生成器?它又是如何工作的?; S5 B2 |4 {4 G 
在我们回答这个问题之前,首先回顾一下一些基础的概率的概念以及学习排列组合的基础知识。这些概念将会帮助我们理解如何计算老虎機的返奖率(RTP)和获胜频率(Hit Rate)。; d6 S9 I5 b- ^; f, ? 
排列组合排列和组合的区别在于,决策的顺序是否对结果产生影响。- 有影响,排列
 - 无影响,组合
 
. B4 m9 \) c  ~( Y( O; e5 r2 ?) C5 u 
  从 n 个元素中取出 k 个元素,k 个元素的排列数量为: 
' D3 r& l0 ~2 Y4 r% L8 }以赛马为例,有 8 匹马参加比赛,玩家需要在彩票上填入前三名胜出的马的号码,那么从 8 匹马中取出 3 排名前三的马,排列的数量为: 
4 O6 F& y$ O: ~( B+ B/ A) q% {5 X8 u3 Q& M. w) \' z& N% H 
那么一共存在 336 种可能性,因此玩家中将的概率为:
