# Normal Distribution

A probability distribution $$N(\mu, \sigma)$$ having the PDF
$\phi_{\mu,\sigma}(x) = \frac{1}{\sqrt{2\pi}\sigma} e^{-\tfrac{(x-\mu)^2}{2\sigma^2}}$
that governs the probability of sums of random variables.
The parameters $$\mu$$ and $$\sigma$$ are equal to the mean and standard deviation respectively.
If $$\mu$$ is equal to zero and $$\sigma$$ is equal to one then it is known as the standard normal distribution.
