# binomial coefficient latex

The combination (n r) (n r) is called a binomial coefficient. are the different ordered arrangements of a k-element subset of an n-set, $$\binom{n}{k} = \binom{n-1}{k-1} +\binom{n-1}{k}$$. where A is the permutation, $$A_n^k = \frac{n!}{(n-k)! Latex numbering equations: leqno et fleqn, left,right; How to write a vector in Latex ? Ak n = n! The usage of fractions is quite flexible, they can be nested to obtain more complex expressions. }}{{k!\left( {n - k} \right)!}} For these commands to work you must import the package amsmath by adding the next line to the preamble of your file You can set this manually if you want. The second fraction displayed in the previous example uses the command \cfrac{}{} provided by the package amsmath (see the introduction), this command displays nested fractions without changing the size of the font. The binomial coefficient can be interpreted as the number of ways to choose k elements from an n-element set.
