请教一道wlab概率题# JobHunting - 待字闺中

电面wlab,被一阿三连问3道概率题,最后一个死活不明白他的问题,最后应该挂了。
向各大牛请教一下。
题目是这样,说obama要竞选总统,进行了两次民意调查:
Poll 1: 6 out of 10 people vote for Obama
Poll 2: 58 out of 100 people vote for Obama
Ask: which one is more indicative that Obama can win the election.
这里indicative是什么意思?我的理解是对underlying distribution的最好估计。阿
三硬说不对。
