Samples of a cast aluminum part are classified on the basis of surface finish (in microinches) and edge finish. The results of 1800 parts are summarized in the table. Let A denote the event that a sample has good surface finish, and let B denote the event that a sample has excellent edge finish. Determine the number of samples in (A∪B) ∪ (A∩B)^(c)
