What is Meant by the Combination?

In mathematics, the combination is defined as the selection of items from a collection or a set where the order of selection does not matter. In combination, the order is not a factor. For example, let us assume three letters A, B and C. From this set, how many ways that the two letters can be selected. For this, each possible selection is a solution of a combination. Here, the complete list of possible combinations is AB, BC, and AC. The formula to calculate the combination is given as follows:

Combination = nCr = n(n-1)(n-2)…(n-r+1)/ r! = n!/ r!(n-r)!= nPr /r!
