Combinations are studied incombinatoricsbut are also used in different disciplines, including mathematics and finance. Formula for Combination Mathematically, the formula for determining the number of possible arrangements by selecting only a few objects from a set with no repetition is expressed in the ...
Repetitions are just repeating numbers. They become important when it comes to choosing the right formula. 123 has no repetitions (each of those numbers is unique). 223 has the number 2 repeated. Allowingrepetitiondepends on your situation. For example: ...

The formula for combination with repetition is as follows: C(n,r)=(r+n−1)!r!(n−1)!C(n,r)=r!(n−1)!(r+n−1)! and for permutation with repetition: P(n,r)=nrP(n,r)=nr In the picture below, we present a summary of the differences between four types of selection ...
