WebJan 13, 2024 · I found a way to calculate the number of possible permutations when the sets s i are disjoint, but not when they are not disjoint. We suppose that the orders of the sets s i are compatible.

A typical example is the formation of numbers from the numbers 2,3,4,5, and finding their number. We calculate their number according to the combinatorial rule of the product: spiral tv series online freeWebSo k1 = 3 because you have 3 Ls. You need to do this for every differnt kind of element. so k2 = 2 (2 Bs) k3 = 3 (3 Ds) Finally the formula is n!/k1!*k2!*k3! Basically, you get the permutations of those 8 letters then rule out those options which are essentially the same. spiral tunnels british columbiaWebHere we select k element groups from n elements, regardless of the order, and the elements can be repeated. k is logically greater than n (otherwise, we would get ordinary combinations).
