12.1.2  Binomial coefficients

The comb or nCr command computes the binomial coefficients.

• comb takes two arguments: n and p, integers.
• comb(n,p) returns (_pⁿ)=C_n^p.

Example

Remark.

The binomial command (see Section 20.4.3) can also compute the binomial coefficients, but unlike comb and nCr it can take an optional third argument, a real number a, to compute the binomial distribution.
