In a certain factory. Three machines produce pencils. For factory evaluation, samples were chosen from the factory was as follows: Type of production 1st machine 2nd machine 3rd machine Good 200-N 200+N 250+N+G Bad 3+G 11-G 2G If one pencil was selected from table, what is the probability to be bad? If the selected sample was bad, what is the probability it was produced from the first machine?
