Final answer:
The probability that a randomly drawn bulb from the carton is not defective is 3/4.
Step-by-step explanation:
The probability that a bulb is not defective can be calculated by considering the total number of bulbs and the number of non-defective bulbs. With a carton of 24 bulbs and 6 defective ones, there are 24 - 6 = 18 non-defective bulbs. The probability, P, that one bulb drawn at random is not defective is given by the total number of non-defective bulbs divided by the total number of bulbs, which is P = 18/24 or 3/4 after simplifying.
