Assume [math]P(E) = \frac{1}{2}[/math], where [math]E[/math] is any event.
By definition of probability, the probability of some event in the universe of events, [math]U[/math], occurring is 1.
Define the event [math]E=U[/math]--that is, [math]E[/math] is the event of any event occurring. By our initial assumption, [math]P(E) = \frac{1}{2}[/math]. However, this contradicts our definition [math]P(E) = P(U) \equiv 1[/math].
[math]\therefore[/math] OP is a faggot. [math]\blacksquare[/math]
