WebIn probability theory, the law of rare events or Poisson limit theorem states that the Poisson distribution may be used as an approximation to the binomial distribution, under certain … WebThe fundamental difficulty is that one cannot generally expect more than a couple of places of accuracy from a normal approximation to a Poisson distribution. For your problem, it may be best to look at the complementary probabilities in the right tail. > 1-ppois(687, 625) [1] 0.006821267 > 1-pnorm(687.5, 625, 25) [1] ...
