## Left Half-Open Interval

$\left ({a, b}\right]$

The notation for a left half-open interval is more commonly seen as:

$\left ({a, b}\right] := \set {x \in S: a < x \le b}$

However, for consistency with other interval notation, its use is deprecated on $\mathsf{Pr} \infty \mathsf{fWiki}$.

The $\LaTeX$ code for $\left ({a, b}\right]$ is \left ({a, b}\right] .
