Normal distribution mathematica

Webde Moivre developed the normal distribution as an approximation to the binomial distribution, and it was subsequently used by Laplace in 1783 to study measurement errors and by Gauss in 1809 in the analysis of astronomical data (Havil 2003, p. 157). The normal distribution is implemented in the Wolfram Language as NormalDistribution[mu, sigma].
