Too much enamel 0.25
Too little enamel 0.2
Uneven application 0.35
No defects noted 0.42
(1) What is the probability of a paint defect?
What is the probability of a paint defect which includes an improper amount of paint?

Because the probabilities add to greater than 1.0, some of them must be joint events (too much enamel and uneven, for instance)
Prob (paint defect)=1Pr(nodefects)=.58
Pr(improper)=.45/.58
