A particular production process used to manufacture gadgets is known to produce 10% defective gadgets. If 900 gadgets are randomly selected and placed in a box, then the number of defective gadgets in this box is distributed as a binomial distribution, with n = 900 and p = 0.10. The mean and standard deviation are = np and = np(1 p). Management is interested in determining the probability that the number of defective gadgets in the box is between 100 and 150. Use the DeMoivre-Laplace theorem to approximate this probability
