Take the code below:
```
\documentclass{beamer}
\setbeamercovered{transparent}
\newcommand{\var}[1]{\operatorname{var}{\!#1}}
\begin{document}
\begin{frame}
\visible<+->{
Intro text}
\begin{align*}
\visible<.->{\Pr(Y_r >0) &= \Pr(Y_r \geq 1) \leq \frac{\mathbb{E}(Y_r)}{1} = \frac{d}{2^r}}
\visible<+->{
\intertext{More text,}
\visible<+->{\Pr(Y_r=0)} & \visible<+->{\leq \Pr(|Y_r-\mathbb{E}(Y_r)| \geq d/2^r)} \visible<+->{\leq \frac{\var(Y_r)}{(d/2^r)^2}} \visible<+->{\leq \frac{2^r}{d}}
}
\end{align*}
\end{frame}
\end{document}
```
How can I have the parts that aren't "visible" yet shown greyed out? I really want this most for the chain of inequalities.

The most important overlay commands are:
- `\only<⟨overlay specification⟩>{⟨text⟩}`: the content won't be present on the overlays not specified
- `\uncover<⟨overlay specification⟩>{⟨text⟩}`: the content is present on all overlays, but dimmed on the overlays not specified (depending on the theme etc, dimmed may also mean not visible at all)
- `\visible<⟨overlay specification⟩>{⟨text⟩}`: the content is present on all overlays, but invisible on the overlays not specified
- `\invisible<⟨overlay specification⟩>{⟨text⟩}`: the content is present on all overlays, but invisible on the overlays specified
- `\alt<⟨overlay specification⟩>{⟨default text⟩}{⟨alternative text⟩}`: shows one or the other depending on the overlays specified
- `\temporal<⟨overlay specification⟩>{⟨before slide text⟩}{⟨default text⟩}{⟨after slide text⟩}` similar to `\alt`, just with two different alt texts
So for your case, this means you want to use `\uncover` instead of `\visible`:
```
\documentclass{beamer}
\setbeamercovered{transparent}
\newcommand{\var}[1]{\operatorname{var}{\!#1}}
\begin{document}
\begin{frame}
\uncover<+->{
Intro text}
\begin{align*}
\uncover<.->{\Pr(Y_r >0) &= \Pr(Y_r \geq 1) \leq \frac{\mathbb{E}(Y_r)}{1} = \frac{d}{2^r}}
\uncover<+->{
\intertext{More text,}
\uncover<+->{\Pr(Y_r=0)} & \uncover<+->{\leq \Pr(|Y_r-\mathbb{E}(Y_r)| \geq d/2^r)} \uncover<+->{\leq \frac{\var(Y_r)}{(d/2^r)^2}} \uncover<+->{\leq \frac{2^r}{d}}
}
\end{align*}
\end{frame}
\end{document}
```
