My degree's in maths so I don't need to google the answer

You switch. Because, when you took your choice, you had a 1/3 chance of being right and a 2/3 chance of being wrong. After the goat is revealed if you were right before (1/3 chance) you will be wrong now, and if you were wrong before (2/3 chance) you will be right now. The revelation of the goat does not affect the decision you already took or the chances of that decision having been right or wrong.
