Chapter 1023： :standard answer (1/2)
”Huh? It still needs an explanation?”
Tao Cheng nodded, ”Because in the eyes of most people, the answer to these two questions is 12.”
”Didn’t you talk about it before? This is a logical reasoning question, and this is still a trial training for the Zhongwei brigade. If there are questions that most people can answer correctly, this is not called logical reasoning. This assessment is also It's too childish.” Lin Yi said:
”So, even if you don't know the answer, writing 12 as an answer is not appropriate.”
Liu Hong and Cao Jiadu nodded in satisfaction.
Even if his answer is wrong, he can start reasoning from here, and his thinking is more flexible than a large number of people.
And Lin Yi's answer made other people suddenly understand.
When answering the question, it was really careless.
Tao Cheng nodded, his thoughts were similar to those of Liu Hong and Caojiadu.
”Then you explain the first question first. From the perspective of biological genes, the probability of the second child, boy and girl is the same, why do you think it is 13.”
”Because the conditions have been given above, we randomly sampled 100 couples with second births. According to the law, 25 families have two boys, 25 families have two girls, and 25 families have one brother and one sister. , 25 pairs of families are an older sister and a younger brother.”
”Tigan said that there is already a boy, and that 25 families with two girls can be excluded. Then the probability of another child being a boy is 2575, which is 13.”
Hearing Lin Yi's explanation, the remaining 35 people all began to think.
Some people quickly understood the reason.
The remaining part is still racking my brains, seemingly not thinking about why this is so.
But Lin Yi has already explained it, and they still don't understand it. That's a question of IQ.
”This calculation process is completely fine.” Tao Cheng said: ”What about the second question?”
”This is even simpler.” Lin Yi said:
”There are three doors. Behind one door is a car, and the remaining two are goats. So the probability of drawing a car is 13, and the probability of drawing a goat is 23.”
Hearing this, everyone nodded, they all understood, there is no problem here.
”Then, you open a door with a goat behind it. Then there is only one door with two hidden goats, but its probability is the same, so the answer is still 23. So, open door number three. , The probability of winning the car is 23.”
”awesome!”
Liu Hong applauded: ”It is reasonable and well-founded. It's really good.”
After listening to it, not only the participants in the trial training suddenly realized, but even Qiu Yuluo looked at Lin Yi with admiration.
How does this guy's head grow?
The idea is so clear?
At this time, Liu Hong walked up to everyone and said:
”Now, the trial training is over. Later, based on your overall results and your own age, you will select the top twelve to join the Zhongwei Brigade. Thank you for your hard work these days. Disband now.”
”Chief, don't you need to do a separate fighting test?” Yuan Hao said.
According to the previous results, he has calculated it, and he can rank 13th.
If you want to be included in the list of the Twelve People's Congress, it will definitely not work.
So he was not reconciled.
”Actually, when we first started the trial training, we planned to add this project to the trial training, but it was cancelled in the end.” Liu Hong said:
”Because we know your situation very well, and your levels are all the same, so such a test is not meaningful, and these three-day tests can better reflect your future development and potential, so we put the actual combat One item is cancelled.”
Liu Hong's answer left Yuan Hao speechless and broke his last hope.
