  • $\begingroup$ Note: I recommend keeping both questions, the linked question / dupe target has more detailed answers and is more general, but this question is nice because it spells it out as "Centre dot" which makes it easier for Google to find. $\endgroup$ – jrh Jan 3 at 21:34

The dot, $\cdot$, in this context is a placeholder for an event or random variable.
