"Witryna8 lip 2016 · 1 Answer Sorted by: 1 Let $W$ be our Gaussian (normal) random variable. Then the cumulative distribution function $F_W (w)$ of $W$ is given by $$F_W (w)=\Pr (W\le w).$$ Note that $F_W (w)$ is the area under the bell-shaped curve from $-\infty$ to $w$. Our normal has mean $0$, so has density function which is symmetric about $0$. " - Origin of normal distribution
