潘尼游戏

连续抛一枚硬币三次，所出现的组合有8种情况，正正正，正正反.......反反反。

潘尼游戏是一方先任选一种组合，然后另一方再从剩余的组合中选择一种。然后开始抛硬币，谁选定的组合先出现谁就获胜。

注意这其中的陷阱，后选一方可以根据先选一方的组合来决定自己的所要选择的组合。诀窍是：后手方选择的组合的后两项是先手组合的前两项，而第一项与最后一项相反。比如先手组合是“正正反”，则后手选择组合“反正正”；先手组合是“正反正”，则后手选择组合“正正反”。

所以这些组合是相生相克的，现在请你统计后手组合对先手组合获胜的概率。-Penny Games

　 Toss a coin three times straight, the combination appears there are eight kinds of circumstances are exactly, are the positive and negative ....... counter-countermeasure against.

　 Penny games are one Choose one of the first combination, then the other and from the remaining portfolio with an alternative. Then start throwing coins, who selected a combination of first and whoever wins there.

　 Note that one of the traps, one after the election the party can choose a combination of the first to determine their composition to be selected. The trick is: FLAC side s choices just get the latter two are combined the first two, but the first and the last one the opposite. For example the upper hand combination is "being positive and negative," then flip choices "Anyway, being"　the upper hand combination "is anyway", then flip choices "are positive and negative."

　Therefore, these combinations are equal grams, and now you just get combined statistical flac combinatio
