A synonym for selection.
An unordered selection of r objects from a set of n (≥r) different objects. The number of different combinations is often denoted by nCr or nCr. In fact,
is the binomial coefficient. Special values are nC0=1, nCn=1, nC1=n.A frequently used relationship is
which is the defining relationship for Pascal's triangle. For ordered selection, see permutation.
1. A subset of a finite set of elements. The number of combinations of n distinct objects taken k at a time is
nCk = n!/[k!(n−k)!]
2. A method of combining functions in a parallel manner (compare composition). For functions f and g,
the combination f × g is such thatwhere S × U and T × V are Cartesian products, and(see ordered pair).
