An oil and gas equipment manufacturing company produces parts for drilling rigs at a steady rate. According to last 12 months of data, 96% of products are within specifications and 4% are defective (Out of Specifications). There is apparently no pattern to the production of defective parts: Thus, we assume that whether or not a part is defective is independent of other parts. What is the probability that there will be no defective parts in a box of 4? What is the probability that there will be 2 or more defective parts in a box of 4?
