for quality control purposes, a company that manufacturers sim chips for cell/ smart phones routinely takes samples from it production process. since it is important that these chips are nearly fault free, one inspection check involves using microscopic equipment to count the number of imperfections on each chip. suppose the average number of imperfections per 1000 sim chip is 3. what is the probability that a sample of 1000 sim chips has 5 imperfections (e = mathematical constant approximated by 2.71828).
