Chapter 71 Congressional Campaign

When the Congressional elections began, H had been worrying for a long time about whether to participate in the election or not.After much deliberation, he couldn't make up his mind, and finally he thought, let's just obey God.So I asked two brilliant fortune tellers A and B for advice, and they answered respectively.

After A finished his speech, he said: "What I said is 60% correct."

After B finishes his speech, he says, "I'm only 30% correct."

As a result, he followed B's divination.

why?

[Answer: Because according to the opposite opinion of B, the correct rate can reach 70%.

B's judgment is only 30% correct, and naturally 70% is incorrect.Under the condition of choosing one of the two, if you go against what he said, you can be 70% correct.And A's judgment is only 60% correct. In comparison, the correct rate is of course smaller.

For a certain judgment, if you deduce it from the opposite side, you will often get unexpected results. ]
