In an electronics laboratory, there are identically looking capacitors of three makes 4, 4₂ and 4, in the ratio 2:3:4. It is known that 1% of 4₁, 1.5% of A₂ and 2% of A, are defective. What percentage of capacitors in the laboratory are defective? If a capacitor picked at defective is found to be defective, what is the probability it is of make 4, ?
