Final answer:
The probability of selecting a defective bulb from the shipment of 30 light bulbs is 1/6.
Step-by-step explanation:
The probability of selecting a defective bulb from the shipment of 30 light bulbs can be calculated using the concept of probability. The total number of light bulbs is 30 and the number of defective bulbs is 5. So, the probability of selecting a defective bulb can be determined by dividing the number of defective bulbs by the total number of bulbs:
Probability of selecting a defective bulb = 5/30 = 1/6
