Permutation Combination 对比 Non-overlapping grouping 的使用情况和统计数据
"Permutation Combination Calculator" is an application that makes it easy to perform calculations for permutations and combinations commonly used in mathematics and statistics. By using this app, even those who are not good at mathematical calculations can easily perform calculations.
The app is equipped with functions for performing permutation and combinatorial calculations. In permutation calculations, you can find the number of cases where r elements are selected from n elements. Combinatorial calculations, on the other hand, allow you to find the number of cases where r elements are selected from n elements, disregarding the order.
In web-based examinations with strict time limits, reducing the time spent on calculation questions can free up time to answer other questions. By allocating your time appropriately and using the "Permutation Combination Calculator", you can take the web-based examinations efficiently and accurately.

Ideal for those who want to do continuous grouping without duplication.
We will respond to the needs you want to group easily in various scenes.
If you enter the number of people for each group(※) and the name you want to group, it will be automatically grouped.
※ If the number of people in the group is even, please enter only that number. (Example: If you want to group two people at a time, enter "2")
If the number of people in the group is not even, please input each number by a hyphen. (Example: If you want to group 3 people, 2 people and 1 person, enter "3-2-1")
Once you can leave a fixed grouping, you can check the overlap with the new grouping.
Also, by setting "avoid duplication" ON, you can combine as much as possible to avoid duplication when new grouping is done.
