1A. A factory produces three types of light bulbs: LED, CFL, and incandescent. The production probabilities for these types of light bulbs are as follows: 50% are LED, 30% are CFL, and 20% are  incandescent. The probability of a light bulb being defective given its type is: 2% for LED, 5% for CFL and 8% for incandescent. If a randomly selected light bulb from the factory’s production line is found to be defective, what is the probability that the defective light bulb is an LED?
