[Tex/LaTex] How to make this expected value symbol?

symbols

I'd like to know how to make in mathmode this fat 'E' as a symbol for expected value?

Symbol that I'm looking for.

Perhaps you need

\mathbf{E}.

Does this solve?

 \documentclass{article}  
 \begin{document}
 \[ \mathbf{E}(\xi)=\int_Z\xi d\rho \]
 \end{document}

You can do something like this.

\documentclass{article}
\usepackage{mathtools}
\newcommand*{\argordot}[1]{%
    \def\arg{#1}%
    \ifx\arg\empty
        \,\cdot\,%
    \else
        #1%
    \fi%
}
\DeclarePairedDelimiterX{\norm}[1]{\lVert}{\rVert}{\argordot{#1}}
\begin{document}
\(\norm{f}\) \(\norm{}\)
