Factory N produces parts,  and proportion 0.15  of those are defective.   Factory J produces parts, proportion 0.10 of those are defective.    Suppose you have a collection of parts from factory N and factory J,  and you know proportion 0.74 of these come from factory N.    If you select one of these parts at random and find it to be defective,  what is the probability it came from factory N?
