6 окт. 2020 г. · We know that a binomial distribution can be approximated with a normal distribution when n∗p is large where n and p are the number of bernoulli trials.

19 нояб. 2016 г. · The rule that p≈1/2 just recognizes that the approximating normal distribution is symmetrical, and the binomial is also symmetrical when p=1/2.
