coefficient. n. 1. (Mathematics) maths. a. a numerical or constant factor in an algebraic term: the coefficient of the term 3xyz is 3. b. the product of all the factors of a term excluding one or more specified variables: the coefficient of x in 3axyz is 3ayz.
The binomial coefficient is the number of ways of picking unordered outcomes from possibilities, also known as a combination or combinatorial number. therefore gives the number of k-subsets possible out of a set of distinct items. For example, The 2-subsets of are the six pairs , , , , , and , so . The number of lattice paths from the origin to a point ) is the binomial coefficient (Hilton and Pedersen 1991).
