Goodnight all. I'll leave you with a math paradox/puzzle:

You flip two coins without looking. Your friend tells you one of them is heads. What is the probability that one of them is tails? Is it 1/2 or 2/3?

It's fucking 1/2 fuck everyone who teaches otherwise they're fucking wrong and I will fight them over this. A coin has a 1/2 chance of being either and the results of another do not fucking effect it god damn.
