In statistics, what does "$Y\mid X=x$" mean? ($Y$ and $X$ are discrete random variables)
"$\mid$" is not "$\div$", right?
Please help me. It will be a great help to me.

By itself $Y|X=x$ has no meaning. But quantities like $E(Y|X=x), P(Y \leq y|X=x)$ have a meaning. Here $|X=x$ means '' given $X=x$' so these quantities are conditional expectations and conditional probabilities.
