A machine normally makes items of which 5 % are defective. The practice of the producer is to check the machine every hour by drawing a sample of size 10, which he inspects. If the sample contains no defectives, he allows the machine to run for another hour. What is the probability that this practice will lead him to leave the machine alone when in fact it has shifted to producing items of which 10% are defective?
