(1) What is the probability of a paint defect?

What is the probability of a paint defect which includes an improper amount of paint?

1 answer

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)=1-Pr(nodefects)=.58

Pr(improper)=.45/.58
