WebA combination is a unique subset chosen from a larger whole. A combination doesn't care about the order of the elements you choose. That is, if you chose A and B from a set of A, B, and C, it's the same as picking B and A. Combinations vs. Permutations. Combinations are related to permutations. In permutations you do care about the order of a ...

WebThe general permutation can be thought of in two ways: who ends up seated in each chair, or which chair each person chooses to sit in. This is less important when the two groups are the same size, but much more important when one is limited. n and r are dictated by the limiting factor in question: which people get to be seated in each of the limited number of … WebThe subsets are symmetric in inclusion/exclusion (and this is why you only have two boxes: the first box represents inclusion and the second exclusion), for example the set { 2 } has a complement, namely { 1, 3 } where the first set is obtained by keeping 2 while the second set is obtained by throwing away 2.
