6.1 Equations

Here is an equation.

$$\begin{equation} f\left(k\right) = \binom{n}{k} p^k\left(1-p\right)^{n-k} \tag{6.1} \end{equation}$$

You may refer to using \@ref(eq:binom), like see Equation (6.1).

6.2 Theorems and proofs

Labeled theorems can be referenced in text using \@ref(thm:tri), for example, check out this smart theorem 6.1.

Theorem 6.1 For a right triangle, if $c$ denotes the length of the hypotenuse and $a$ and $b$ denote the lengths of the other two sides, we have $$a^2 + b^2 = c^2$$
