Math : Supporting Algorithm
Recent U.S. election
Very popular
My grandson’s teacher also raised a topic of current affairs
During the election
Red voters accounted for 30%
Blue voters accounted for 30%
White voters accounted for 40%
A candidate
According to polls
The support among red voters is 20%
The support among blue voters is 80%
The support among white voters is 60%
How many is the support of this candidate among all voters?
The algorithm is as follows
30% X 20% + 30% X 80% + 40% X 60%
= 6% + 24% + 24%
=54%
PS:
A red voter refers to a candidate who has voted for a red party over the years.
Only when the red ones are too bad, or the blue ones are too Good,
Then he changed to his camp. Basically, he alway voted for the red.
数学-支持度的算法
最近的美国大选
非常的热门
小孙子的老师也出了一个时事的题目
大选之中
红色的选民占了30%
蓝色的选民占了30%
白色的选民占了40%
某候选人
根据民调显示
在红色选民之中的支持度是20%
在蓝色选民之中的支持度是80%
在白色选民之中的支持度是60%
请问这位候选人在所有选民之中的支持度是多少?
算法如下
30% X 20% + 30% X 80% + 40% X 60%
= 6% + 24% + 24%
=54%
PS:
红色选民是指,历年以来,他都是投票给红色的政党之候选人,
只有当红色的太差劲, 或者蓝色的太过优秀,
才会改投他营, 基本上, 他都是投给红色的.
