Let X be the number of defective parts produced on acertain production line. It is known that, for a given lot,X is a binomial random variable, with mean equal to240 and variance 48.a. What are n, p, and q?b. What is the probability that at most 2 of the parts inthis lot are not defective?c. What is the probability that at least 10 parts aredefective?
