I was wondering if I could get some help with this. I want to align the heights of fraction and the summation. The summation is positioned too low compared to the fraction. How can I acheive this?
\documentclass[12pt,a4paper]{article}
\begin{document}
\[\Lambda_{entry} =\frac{\psi/(1-\delta)}{\psi/(1-\delta) + m_{I}} + \frac{m_{I}(1-\Phi)}{\psi/(1-\delta) + m_{I}} \sum^{}_{(\tilde{g},\tilde{b}) \in \{(g,b)\}}\hspace{0.1em}f_{\tilde{g},\tilde{b}-1}\]
\end{document}
