The average outgoing quality (AOQ) is calculated using the formula AOQ = (p * (1 - P(accept))) where p is the proportion of defectives and P(accept) is the probability of accepting the batch. With n = 20, c = 1, and p = 0.15, the probability of accepting the batch can be calculated using the binomial distribution. The AOQ is approximately 0.0263.
