Show that the density of the sum of two independent standard normal random variables is given by:
f(x) = 1/(2√π) * e^(-.25x^2)
So far I know that the random variable X has a standard normal distribution if its density is given by:
f(x) = (1/√(2π)) * e^(.5x^2)
However, I'm unsure of where to go from here...
