Typo - Probability II

[geneh0]

The currently published version of the textbook currently reads:
"Multiplication rules deal with intersections ($\cup$) of events."

I believe this should be:
"Multiplication rules deal with intersections ($\cap$) of events."

I think it also has extraneous pairs of "$" in the 3 subsequent equations, or at least aren't properly centered.

Thanks for catching this! Will update and push.
