# Question: A chain sampling plan is used for the inspection of lots

A chain-sampling plan is used for the inspection of lots of size N = 500. The sample size is n = 6. If the sample contains no defectives, the lot is accepted. If one defective is found, the lot is accepted provided that the samples from the four previous lots are free of defectives. Determine the probability of acceptance of a lot that is 2% defective.
