◆NUMBERS GAME
You are playing a numbers game where your computer generates a random number
until the number is odd. Your score will be the number of even numbers
generated.
If you play this game many times what will be the average of your scores?
Note:
The numbers generated are equally likely to be odd or even.
你玩一個數字遊戲:讓電腦不斷產生亂數直到出現一個奇數。
你的分數是所產生的偶數的個數。
若你玩這遊戲許多次,試問平均分數為何?
註: 所產生的數字是奇數或偶數的機會相同。
