題目不懂= =
6. (10%) A pair of fair dice is continuously rolled until either a 1 or a 6 appears at which point the experiment stops. What is the probabilitythat the experiment was stopped not because of 1's appearance? 是說兩個骰子都不是1就是6時停嗎?
不知道對不對 參考看看
回覆刪除感覺題目上是說
一對公平的骰子
如果丟出1 or 6就暫停
請問在這情況下
不是1 卻暫停的情況是多少
原本是1或6 共有11種情形
如果還要不是1的情況 那就有5種
所以是5/11
