Question:
Fasteners used in a manufacturing process are shipped by the supplier to the manufacturer in boxes that contain 20 fasteners. Because the fasteners are critical to the production process, their failure will cause the product to fail. The manufacturing firm and the supplier have agreed that a random sample of 4 fasteners will be selected from every box and tested to see if the fasteners meet the manufacturer’s specifications. The nature of the testing process is such that tested fasteners become unusable and must be discarded. The supplier and the manufacturer have agreed that if 2 or more fasteners fail the test, the entire box will be rejected as being defective. Assume that a new box has just been received for inspection. If the box has 5 defective fasteners, what is the probability that a random sample of 4 will have 2 or more defective fasteners? What is the probability the box will be accepted?
