WebFor instance, a subset consisting of $1$, $2$, and $3$ is selected six times: once as 1-2-3, once as 1-3-2, once as 2-1-3, once as 2-3-1, once as 3-1-2, and once as 3-2-1. Well, there are $k$ items, and so there are $P^k_k$ ways of ordering them; this is exactly $k!$ ways. So we counted each $k$-subset $k!$ ways.

WebThe argument given is the total number of subsets for a set of n elements. Combinations, on the other hand, count the number of subsets of a given size. For example, consider the set { 1, 2, 3 }. There are 2 3 = 8 total subsets (of all sizes ), which are { ∅, { 1 }, { 2 }, { 3 }, { 1, 2 }, { 1, 3 }, { 2, 3 }, { 1, 2, 3 } } Web2 hours ago · The RMS Titanic was one of the largest ships in the world when it set sail from England to the United States on April 10, 1912 — but it sank four days later.
