A normal distribution of a random variable X with mean and variance is a statistic distribution with probability density function (pdf) (1) on the domain . While statisticians and mathematicians uniformly use the term "normal distribution" for this distribution, physicists sometimes call it a Gaussian distribution and, because of its curved ...

Use your calculator to help evaluate a binomial probability. If X is B(n, p), find µx and (x (that is, calculate the mean and variance of a binomial distribution). Use a Normal approximation for a binomial distribution to solve questions involving binomial probability. Vocabulary: Binomial Setting – random variable meets binomial conditions
