P( X = 1) =
4 1 1 3 4 4 4 0 The results from the binomial approximation are close to the probabilities obtained in Exercise 397. c) Assume X has a binomial distribution with n = 4 and p = 0.2. Consequently, P(X = 1) and P(X = 4) are the same as computed in part b. of this exercise. This binomial approximation is not as close to the true answer as the results obtained in part b. of this exercise. d) From Exercise 310...
