Suppose that 8% of products on a production line are defective. An inspector randomly selects these products one at a time until he finds a defective product. There are two parts to this problem. a. What is the probability that at least 12 products must be inspected in order to find the first defective product? Start this part of the problem by stating what X is in words and giving its complete distribution (i.e., write "X = ____" and "X...

Electric motors coming off four assembly lines are pooled for storage in a common stockroom, and the room contains an equal number of motors from each line. Motors are periodically sampled from that room and tested. It is known that 10% of the motors from line I are defective, 5% of the motors from line II are defective, 3% from line III are defective and 1% from line IV are defective. If a motor is randomly selected from the stockroom...
