I am trying to group equations and reference them inside brackets, I tried using \label but it doesn't work, I tried split:
\[\begin{cases} \begin{split} \prob_1 \Big[\mathrm{Inf}_{A,1}^{+}(h^*) > \frac{1}{2} + \frac{\epsilon}{2} \Big] \leq \exp{\Big(- \frac{d \epsilon^2}{18}\Big)} \label{res1plus1} \end{split} \\ \begin{split} \prob_1 \Big[\mathrm{Inf}_{A,0}^{-}(h^*) > \frac{1}{2} + \frac{\epsilon}{2} \Big] \leq \exp{\Big(- \frac{d \epsilon^2}{18}\Big)} \label{res1minus0} \end{split} \\ \begin{split} \prob_1 \Big[\mathrm{Inf}_{A,0}^{+}(h^*) > \frac{1}{2} - \frac{\epsilon}{2} \Big] \leq \exp{\Big(- \frac{d \epsilon^2}{2}\Big)} \label{res1plus0} \end{split} \\ \begin{split} \prob_1 \Big[\mathrm{Inf}_{A,1}^{-}(h^*) > \frac{1}{2} - \frac{\epsilon}{2} \Big] \leq \exp{\Big(- \frac{d \epsilon^2}{2}\Big)} \label{res1minus1} \end{split}\end{cases}\]
However, I get what i want but with no reference, as shown here:
