# BinomialCoefficient Command

From GeoGebra Manual

- BinomialCoefficient( <Number>, <Number> )
- Calculates the binomial coefficient n \choose r . The first Number represents all elements
*n*and the second Number represents the selected elements*r*. **Example:**`BinomialCoefficient(5, 3)`

yields*10*.

**Hint:**If your input in the CAS View contains undefined variables, then this command yields a formula for the binomial coefficient.**Example:**`BinomialCoefficient(n, 3)`

yields \frac{n^{3} - 3 n^{2} + 2 n}{6}.

**Note:**See also NPr command.
