In a nationwide poll, N people were interviewed.If 14 of them answered "yes" to question 1, and of those, 13 answered "yes" to question 2, which of the following expressions represents the number of p

我在kmf网有做模考，这是在一次模考中遇到的题目，答案是(11/12)N，我看了下面一个人给出的解析，先是求出了answered "yes" to both question1 and question2的人数是(1/12)N，到这里我是能计算出来的，但是它接下来直接就用N-（1/12）N得出了答案，我没想通，百度搜了一下也没有搜到更好的解答，想知道这道题是不是有问题..还是我哪里没理解到位
