◆Dice Game
You are playing a dice game with your friend by rolling two standard dice.
You will win when two consecutive outcomes are 7. Your friend will win when
three consecutive outcomes are in increasing order. You will continue rolling
until one of you will win. What is the probability that you will win?
Examples:If the outcomes are 10,4,6,6,7,7 you will win. If the outcomes are
7,3,7,9 your friend will win.
Enter your answer as a simplified fraction. Example:12/23
你和你的朋友用兩個標準的骰子玩一個遊戲。
你的勝利條件是連續兩次骰出7;你朋友的勝利條件是連續三次骰的結果是遞增的。
在分出勝負之前骰子會持續投擲下去。
試問你取勝的機率是多少?
舉例: 若依序骰出 10,4,6,6,7,7 則你獲勝;若依序骰出 7,3,7,9 則你朋友獲勝。
答案以最簡分數回答,如 12/23。
