At least one defective iphone it has been reported that 20% of iphones manufactured by foxconn for a product launch did not meet apple’s quality standards. an engineer needs at least one defective iphone so she can try to identify the problem(s). if she randomly selects 15 iphones from a very large batch, what is the probability that she will get at least 1 that is defec- tive? is that probability high enough so that she can be reasonably sure of getting a defect for her work?
