In a certain assembly plant, three machines B1, B2, and B3 make 30%, 25% and 45% respectively, of products. It is known from past experience that 3%, 3% and 2% of the products are made by each machine, respectively are, defective. Now, suppose that a finished product is randomly selected. What is the probability that it is defective?
