Don't You Just Hate Probability?
From Geekosystem: Probability was my least favorite math unit, and this is why. Because even the questions that they assured me “make sense” look like this. It’s multiple choice so, obviously, the answer is 25%, but that’s there twice, so obviously the answer is 50%, but that’s only 25% of the answers. So, obviously, the answer is: There is no answer. If the answer is 25%, then the answer is 50%, in which case the answer is 25%. Lather, rinse, repeat, crash to blue screen.
