# --description--
|
||
|
||
两名玩家分享一个无偏见的硬币并轮流玩“The Race”。在玩家1的回合中，他扔了一次硬币：如果它出现在Heads，他得分为1分;如果它出现Tails，他什么都没得分。在玩家2的回合中，她选择一个正整数T并将硬币投掷T次：如果它出现在所有的头上，她得到2T-1分;否则，她没有得分。玩家1排在第一位。获胜者是第一个达到100分或更多分。
|
||
|
||
在每次转弯时，玩家2选择硬币投掷的数量T，以最大化她获胜的概率。
|
||
|
||
玩家2获胜的概率是多少？
|
||
|
||
将您的答案四舍五入到0.abcdefgh形式的八位小数。
