不好意思有一個很簡單的問題一直搞不懂>< A pair of four sided dice is rolled and the sum is determined. In a sequence of rolls the probability that a sum of 3 is rolled before a sum of 5 is rolled can be thought of as the conditional probability of a sum of 3 given that a sum of 3 or 5 has occurred. 雖然上面教了方法但是我搞不懂為什麼可以這樣解釋懇請高手賜教謝謝 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 96.251.58.58
