A factory checks products for two features. Event AA is that a randomly chosen product is waterproof, and event BB is that it is scratch-resistant. Given P(A)=0.52P(A)=0.52, P(B)=0.41P(B)=0.41, and P(A∩B)=0.18P(A\cap B)=0.18, what is the probability that AA or BB occurs (inclusive or: waterproof, scratch-resistant, or both)?
