Super D is a major video distributor that purchases blank DVDs from two sources: Disk Makers, which provides 62% of the DVDs, and Media Supply, which provides the remaining 38%. Historically, 3% of the DVDs Super D has purchased from Disk Makers have been defective, whereas 2% of the DVDs purchased from Media Supply have been defective. A randomly selected DVD is found to be defective.

Use Bayes’ Theorem to determine the probability that the DVD came from Disk Makers.
