Operati A diagnostic test for a certain disease is applied to n individuals known to not have the disease. Let X- the number among the n test results that are positive (indicating presence of the disease, so X is the number of false positives) and p - the probability that a diseas + test result is positive (i.e., p is the true proportion of test results from disease-free individuals that are positive).
