The normal distribution law describes a distribution of data which are arranged symmetrically around a mean. The majority of data is close to this average, others are moving away gradually. This forms a normal distribution bell curve also called Gaussian curve.
Many physical quantities approach this normal distribution often described as the law of natural phenomena.
Eventhough there are many lawsofprobability, aphenomenonbornof chance, reiteratedmanytimes, followsa probabilitythat tends towardsthe normal distribution. This theoremis illustratedwiththe binomial distribution.
