A binomial coefficient C(n, k) also gives the number of ways, disregarding order, that k objects can be chosen from among n objects more formally, the number of k-element subsets (or k-combinations) of a n-element set. A binomial coefficient tells us how many ways we can choose k things out of n total things. The binomial coefficients can be arranged to form Pascal's triangle, in which each entry is the sum of the two immediately above. So for example, if you have 10 integers and you wanted to choose every combination of 4 of those integers.
