实在无计可施 上课新东方讲义上的题 实在不知道咋做
上题:
favorable unfavorable not sure
candidate M 40 20 40
candidate N 35 35 35
the table above shos the results of a survey of 100 voters who each responded "Favorable" or "Unfavorable" or "Not Sure" when asked about their impressions of Candidate M and of Candidate N. What was the number of voters who responded "Fvorable" for both candidates?
(1) the number of voters who did not respond "Favorable" for either candidate was 40.
(2) the number of voters who responded "Unfavorable" for both candidates was 10.
数学的一道DS题
觉着语法区人气旺就跑这里问数学了
实在绕晕了 这里需要考虑 not sure M 却 sure了 N 和 not sure N 却 sure了 M 以及俩都不sure 这些个情况么 求NN 大神 各种神仙妖魔鬼怪大大们来帮忙 希望能给个越详细越好的解释 包括解题思路 G菜在这里先谢谢了~~~跪谢!! |
