math-modesymbols
I am studying theory at university, and the lecturer uses this symbol for elementary probability:
I want to use it in math mode, but the best suggestions I got from http://detexify.kirelabs.org/classify.html was:
\usepackage[T1]{fontenc}
\TH
textmode
and
\usepackage{ tipa }
\textthorn
textmode
What i need is this symbol, sans serif, italic, in math mode.
How can i reach it?
The letters font should be a font encoded as OML, not OT1; you can use CMBright for those and for the OMS family; a decent substitute for the large symbols can be Iwona:
\SetSymbolFont{operators} {sans}{OT1}{cmss} {m}{n}
\SetSymbolFont{letters} {sans}{OML}{cmbrm}{m}{it}
\SetSymbolFont{symbols} {sans}{OMS}{cmbrs}{m}{n}
\SetSymbolFont{largesymbols}{sans}{OMX}{iwona}{m}{n}
This answer comes following discussion in the comments to the question, to which I refer the reader. I pointed out that my solution at Upright Greek font fitting to Computer Modern works directly at unslanting a font (it is based on Bruno's answer at Shear transform a "box"). I show there how to apply it to greek letter forms, but noted that it only applies to pdflates, whereas the OP had lualatex invocations in the preamble.
The OP then tells me that the \unslant method works in lua as well (halle-lua-jah), but that the underlying \slantbox has a problem accepting the color of tikz nodes. That was news to me, since \slantbox accepts color just fine as part of a \textcolor argument, or following a \color declaration.
I then came across a pgf bug report, https://sourceforge.net/p/pgf/bugs/362/, that would seem to be related to the problem. Since I can't solve that problem myself, I looked for a workaround.
Heiko's answer at How to save the current colour shows a cool technique of \colorlet{slantcolor}{.} to save the current color (before going into the \mbox, and then I just re-issued a \color{slantcolor} inside the \foobox. That seemed to fix the problem.
To recap, the \unslant method allows existing italic letters to be made upright in the same font design, and the \colorlet fix allows this solution to work with colored tikz nodes. The overall approach works with pdflatex and lualatex.
\documentclass{article}

\usepackage[scaled=0.95]{helvet}

\usepackage{tikz}
\usepackage{scalerel}
\newsavebox{\foobox}
\newcommand{\slantbox}[2][0]{\colorlet{slantcolor}{.}\mbox{%

\pdfsave
\pdfsetmatrix{1 0 #1 1}%
\llap{\usebox{\foobox}}%

\newcommand\unslant[2][-.2]{%

\ThisStyle{\slantbox[#1]{$\SavedStyle#2$}}%
\mkern-1mu%

\newcommand\upmu{\unslant\mu}

Upright greek in math mode: $\mathrm{\mu}$, $\upmu$,
\begin{tikzpicture}
\node[color=red,] {$\upmu$$\mu$};
\end{tikzpicture}

The Comprehensive list shows a bundle of different
\thornsymbols, depending on various packages.The table below gives an example of some of the commands.
There might be some warnings, especially for the
\itshapefontshape, since this shape is not available for all fonts/symbols
