12 nov 2019 · Although it seems strange, under certain circumstances a (continuous) normal distribution can be used to approximate a (discrete) binomial
In 1733, Abraham de Moivre presented an approximation to the Binomial distribution He later (de Moivre, 1756, page 242) appended the derivation
Normal Approximation to the Binomial distribution IF np > 5 AND nq > 5, then the binomial random variable is approximately normally distributed with mean µ =np
