Do not use {n choose k} in LaTeX (it is a plain TeX command). The recommended way in LaTeX is usepackage{amsmath} in the preamble and then binom{n}{k} . (You have then also tbinom and dbinom for text and display styles also.)

How do you write a binomial coefficient in LaTeX?
Using fractions and binomial coefficients in an expression is straightforward.
- The binomial coefficient is defined by the next expression: [ binom{n}{k} = frac{n!
- Fractions can be used alongside the text, for example ( frac{1}{2} ), and in a mathematical display style like the one below: [frac{1}{2}]
How do you write fractions in LaTeX?
Fractions and binomial coefficients of math equations in LaTeX are written using the frac and binom command respectively. We use the frac command to display fractions. The expression between the first pair of brackets is the numerator and in the second is the denominator.
How do you write N in LaTeX?
You will need to use an external package for this natural numbers symbol. Latex has four packages and each package has the same command to denote the ℕ symbol. And the capital letter N must be passed as an argument in mathbb{N} command. And the natural numbers are written in the form of a set of positive numbers.

What is choose in probability?
In short, it is the number of ways to choose two elements out of n elements. For example, ‘4 choose 2’ is 6. If I have four elements – A, B, C and D – I can select two elements in the following ways – {A, B}, {A, C}, {A, D}, {B, C}, {B, D} and {C, D}.
How do you align equal signs in LaTeX?
The eqnarray environment lets you align equations so that, for example, all of the equals signs “=” line up. To do this, put ampersand “&” signs around the text you want LaTeX to align, e.g. Each equation can be labelled separately, just put the label command after the relevant equation.
How do you write slanted fractions in LaTeX?
The sfrac command is used to create a slanted line, while the frac command is used to create the straight line between the numerator and the denominator. To implement sfrac, we need to use the xfrac package. The package is written as usepackage{xfrac}.
How do you write infinity in LaTeX?

How do you write columns in LaTeX?
LaTeX Multiple Columns
Text with two or double columns can be created by passing the parameter twocolumn to the document class statement. If you want to create a document with more than two columns, use the package multicol, which has a set of commands for the same.
How do you find the choose function?
“n” is the number of items that are in the set (4 in this example); “r” is the number of items you’re choosing (2 in this example): C(n,r) = n! / r! (n – r)! = 4! / 2!
How do you reference equations in LaTeX?
- You can simple use begin{align}x+ylabel{eq:1}end{align} and later use ref{eq:1} or eqref{eq:1} to reference to the equation.
- You can put one label on each line and refer to a particular equation.
How do you left align in LaTeX?
The switch command raggedright will also produce left-aligned text, but the behaviour is different; in this case the text will be left-aligned from the point where the command is declared till another switch command is used. This is more suitable to align long blocks of text or the whole document.
