Question

What is the normal probability distribution function? State its properties. b) Write down the distribution functions of the Binomial distribution and Poisson distribution. When is a Poisson distribution an approximation of Binomial distribution? Obtain the mean and variance of the Binomial and Poisson distribution

Answer 1

probability theory, the normal (or Gaussian or Gauss or Laplace-Gauss)distribution is a very common continuous probability distribution.Normal distributions are important in statistics and are often used in the natural and social sciences to represent real-valued random variables whose distributions are not known
