At a certain factory, the same products are manufactured on two independent lines A and B. Line A manufactures 60% of all the products, and line B manufactures 40%. Of the products manufactured on line A, 2% are defective, and of the products manufactured on line B, 1% are defective. When a single product manufactured at this factory was selected randomly, it turned out that this product was defective. What is the probability (percentage) that this product was manufactured on line A?
