 It has been reported that 9 % of phones manufactured by a certain company for a product launch did not meet the quality standards. An engineer needs at least one defective Phone so she can try to identify the problem(s). If she randomly selects 13 phones from a very large batch, what is the probability that she will get at least 1 that is defective? Is that probability high enough so that she can be reasonably sure of getting a defect for her work? Probability that at least one phone out of a sample of 13 is defective is (round to 4 decimal places). [a] Is the probability high enough so that she can be reasonably sure of getting a defect for her work? Type Yes or No in the box below.  [b]
