Final answer:
The question concerns finding the probability of multimedia software being defective, which involves using the complement rule to determine the likelihood of software failure.
Step-by-step explanation:
The question asks about the probability that multimedia software manufactured by a company is defective. When dealing with probabilities, we often use the complement rule, which states that the probability of an event not occurring is 1 minus the probability that it does occur. For example, if the probability of a computer component being defective is 0.02, as mentioned in a reference example, the probability of a computer component being non-defective would be 1 - 0.02 = 0.98. In the options given for the probability of software being defective (0.9957, 0.9987, 0.9970, 0.01), we would look for a probability close to this and interpret that the company would want to know the likelihood of a software defect, which is generally a low probability event.
