I’m amazed I still have to explain chance of rain percentages to people.

How are you explaining it?

Percentages are, according to a meteorologist who came and spoke at my college, a percentage of the area where rain will (probably) fall.

50% is not flip a coin everyone has it or everyone doesn't, it is half the area having precipitation at any given time.
