n. 1. (Mathematics) maths. a. a set the members of which are all members of some given class: A is a subset of B is usually written AâB. b. proper subset one that is strictly contained within a larger class and excludes some of its members.
Because the number of subsets with k elements one can form from a set with n elements is nCk, and the total number of subsets of a set is the sum of the numbers of possible subsets of each size, it follows that nC0+nC1+nC2+ â¦ +nCn = 2.
