In a factory, robots 1, 2, and 3 produce wires of the same length, with 2%, 1%, and 3% defective wires, respectively. Of the total production of wires in the factory, the robots produces 35%, 25%, and 40%, respectively. If a wire is selected at random from the total wire produces in a day and is found to be defective, what is the probability that it was produced by robot 1?
