How can I type the Mathematica symbols “Distributed” and “Conditioned”?
I've got the feeling that these two symbols do not exist in the unicode standard. So I would recommend to draw them by yourself in TikZ or to copy the images and include them using the package
If you can find any other references for these symbols, you can submit them to unicode or to the font developer of your choice.
Barbara Beeton surmises that the "Conditioned" symbol could be the unicode
The normal sign for distributed is a standard tilde. So maybe you do not even need the exotic symbol of Mathematica. Search this homepage for normal, wide, and bold tildes in all forms and colors...
