In July 2011, the state of Florida started testing all welfare recipients for the use of illegal drugs. Statistics suggest that some 8% of adult Floridians use illegal drugs; let us assume that this is true for welfare recipients as well. Imagine that the drug test is 90% accurate, meaning that it gives the correct response in nine cases out of 10. c) What is the probability that a randomly selected Floridian welfare recipient has a positive test.
