Super D is a major video distributor that purchases blank SD Drives from two sources: Disk Makers, which provides

69%

of the SD Drives, and Media Supply, which provides the remaining

31%.

Historically,

7%

of the SD Drives Super D has purchased from Disk Makers have been defective, whereas

6%

of the SD Drives purchased from Media Supply have been defective. A randomly selected SD Drive is found to be defective. Use Bayes' Theorem to determine the probability that the SD Drive came from Disk Makers.
