In a certain factory, machines I, II, and III are all producing springs of the same Q.2. length. Machines I, II, and III produce 3%, 2%, and 5% defective springs, respectively. Of the total production of springs in the factory, Machine I produces 30%, Machine II produces 25%, and Machine III produces 45%. If one spring is selected at random from the total springs produced in a given day, determine the probability that it is defective.
