Mathematics is present in your lives in everything.

I going celebrate PI-day asking you a interesting thing. Did you know?

Pi also crops up in probability. The function f(x)=e-x², where e=2.71828… is Euler’s number, describes the most common probability distribution seen in the real world, governing everything from SAT scores to locations of darts thrown at a target. The area under this curve is exactly the square root of π.
