Let X be the number of defective parts produced on a certain production line. It is known that, for a given lot, X is a binomial random variable, with mean equal to 240 and variance 48. a. What are n, p, and q? b. What is the probability that at most 2 of the parts in this lot are not defective? c. What is the probability that at least 10 parts are defective?
