What distribution does $X/Y$ have if $X$ and $Y$ are normal distributed independent variables?

$begingroup$


Let $X,Ysim N(0,1)$ iid. What distribution would the variable $frac{X}{Y}$ follow? Intuitively it would have an expected value of $1$. Or would it?

    It's a Cauchy distribution, which has no well-defined mean: en.wikipedia.org/wiki/Cauchy_distribution
