题目如下: In the game of Parcheesi each player rolls a pair of dice on each turn. In order to begin the game,the player must roll a five on at least one dice,or a total of five on both dice.Find the probability that the player does not get to begin the roll on either their first or second rolls. 他大概是在说，要让比赛开始，就必须要掷一对骰子，并且至少有一颗骰子点数为5 或者是两颗骰子点数合为五，才能让比赛开始 要让比赛开始的机率我算出来是11/36+4/36=5/12 但他最後问的意思我就不太清楚了 他是问说算出在第一次投掷或者第二次投掷，不能让比赛开始的机率吗 这题是有两个人轮流骰骰子吗? --
