I’m trying to type the formula for conditional probability and I’m having trouble finding how to make a pipe (|) symbol. The character itself makes a logical or.

So my question is, how do I write P(A|B)?

To have it behave like an operator (which may sometimes be desirable) you can either use the `divides`

operator (which uses the pipe symbol) or the “binary operator modifier” `boper`

.

Not sure that this will ever be an issue in the context of “A, given B”, but anyway, here goes:

`P(A divides B)`

`P(A boper | B)`

Those are rendered almost the same. As far as I can tell, the `boper`

version adds a little more spacing around the operator than the `divides`

operator, but it is hardly noticeable unless you compare them side by side.

`P(A boper | B)`

is really good. It produces the same MathML then `P(A mline B)`

, but the StarMath code carries the mathematical meaning much better.

Nevermind, I figured it out, you just put it in quotation marks:

P( A “|” B )

or as `P(A mline B)`
