Row test question bank: answer to row test mathematical operation simulation question

1. [Answer] B. Zhonggong analysis: The title describes that the same 10 vouchers are distributed to 3 advanced workers, which are different stacks of the same element, but do not meet the condition of "each object is divided into at least one" of the partition model, but we can make it meet through conversion, that is, first give each advanced worker one voucher, and then leave 7 vouchers, Allocate at least one piece to three advanced workers, using the formula, there are So select option B.

2. [Answer] C. Zhonggong's analysis: In this question, the water supply company is required to choose a plan of two days without water supply in seven days. If we directly calculate or enumerate all the eligible schemes, we can achieve the purpose of selecting the correct answer. However, it is relatively complicated and does not meet the requirement of saving time. Therefore, we may consider from another perspective that to make the two days of water supply interruption disconnected, we can first consider five days of other water supply without requirements. After the water supply interruption is arranged, insert the two days of water supply interruption into six spaces formed by the five days of water supply interruption, and then the water supply interruption time must be disconnected. Therefore, there are The water cut-off plan is proposed.

3. [Answer] D. Zhonggong's analysis: This topic describes the situation of male and female students' speeches. It is required that the female students can not make continuous speeches in the topic, and the calculation can be carried out by inserting space. First consider the 10 boys who have no requirements, and then insert the 3 girls who cannot make continuous speeches into the 11 vacancies formed by the boys. Then the girls must not be connected. Therefore, there are Three speech sequences.
