The probability that the bulb is working is 0.92. A customer in a store chooses a random package containing two of these bulbs. Find the likelihood that both bulbs will be defective.
We find the probability that the bulb is defective:
1-0.92 = 0.08
Then we multiply 0.08 by 0.08 since the probability of buying two bulbs at once is less than buying one defective one by exactly 0.08, that is, the probability of buying one defective bulb.
Answer: 0.064
