When I use the following code on stats.stackexchange.com (which is powered by MathJax) the \le
does not render properly. Is this a bug in MathJax or am I not using the \le
symbol properly?
$X_3 =
\begin{cases}
X_{31} & \mbox{if }Y_1 Y_2 \mbox{ > 0} \\\
X_{32} & \mbox{if }Y_1 Y_2 \mbox{ \le 0}
\end{cases}$

use
\le
in math mode, e.g.\mbox{if $Y_1 Y_2 \le 0$}
(yes, that's math mode inside text)use T1 font encoding to get the > symbol correctly typeset in text mode:
\usepackage[T1]{fontenc}
Otherwise, with standard OT1 encoding, the output wouldn't be > except you use math mode as well:$>$
On standard LaTeX you should also use
\text{...}
rather than\mbox{...}
.
