[Tex/LaTex] P symbol of probabilities

symbols

I cannot find this P:

My \mathbb{P} and \mathcal{P} are:

I have found similar questions related to finding specific symbol or some P, but none of them looks for this P or shows a way to look for your specific symbol.

Best Answer

You can try this:

\documentclass[12pt]{article}
\begin{document}
    I\kern-0.15em P
\end{document}

If you want to use it in math mode several times, you may want to create a macro.

\documentclass[12pt]{article}
\usepackage{amsmath}
\newcommand{\probP}{\text{I\kern-0.15em P}}
\begin{document}
    $\probP(A)=0.5$
\end{document}

[Tex/LaTex] How to negate a specific symbol

There are a number of ways to achieve the negation of a symbol:

Follow the guidelines in How to look up a symbol or identify a math symbol or character? to see whether such a symbol already exists.

This is usually the best course of action, since the symbol would have been constructed to match certain specification (say, placement and height/depth of negation symbol). If such a symbol is only available in a different font, then consider including only that symbol by following the instructions in Importing a Single Symbol From a Different Font.
```
\documentclass{article}
\usepackage{amssymb}% http://ctan.org/pkg/amssymb
\begin{document}
\[
  a \neq b \nparallel c \nvDash d \nprec e
\]
\end{document}
```
For a symbol \mysymbol, try \not\mysymbol. \not is a zero-width math relation that is set "on the right" of where it's called. As such, it visually overlaps the typical math relation/symbol. Not always perfect, but works in general.
```
\documentclass{article}
\begin{document}
\[
  a \not= b \not\geq c \not\sim d \not\approx e \not\in f
\]
\end{document}
```

centernot works well when symbols are somewhat wider than usual, yet you still want the regular \not-like visual.

enter image description here

\documentclass{article}
\usepackage{centernot}% http://ctan.org/pkg/centernot
\begin{document}
\[
  a \not= b \centernot= c 
    \not\parallel d \centernot\parallel e 
    \not\longrightarrow f \centernot\longrightarrow g
\]
\end{document}

The cancel package draws a diagonal line across a symbol to "cancel" it.

enter image description here

\documentclass{article}
\usepackage{centernot,cancel}% http://ctan.org/pkg/{centernot,cancel}
\begin{document}
\[
  a \not= b \centernot= c \mathrel{\cancel{=}} d
    \not\longrightarrow e \centernot\longrightarrow f \mathrel{\cancel{\longrightarrow}} g
\]
\end{document}

Other methods include using graphics packages like tikz or pstricks to draw rules in specific locations across a symbol/construction.
