Composite sampling is a way to reduce laboratory testing costs. A public healthdepartment is testing for possible fecal contamination in public swimming pools. In thiscase, water samples from 5 pools are combined for one test, and further testing isperformed only if the combined sample shows fecal contamination. Based on pastexperience, there is a 3% chance of finding fecal contamination in a public swimmingarea. What is the probability that a combined sample from 5 swimming pools has fecalcontamination? Recall that P(A) +P(not A) = 1.0.
