In the figure belоw, we visuаlize the blооd pressure distribution аmong the heаlthy population and the distribution among the population with hypertension (high blood pressure). We split the histograms into 4 labeled regions: A is the number of individuals in the healthy population with blood pressure < 130; B is the number of individuals in the healthy population with blood pressure >= 130; C is the number of individuals in the hypertension population with blood pressure < 130; D is the number of individuals in the hypertension population with blood pressure >= 130. Consider the rule: an individual is diagnosed with hypertension if the blood pressure level is >= 130. The false positive rate of this method is equal to _______. Express your answer as a formula in terms of A, B, C, D (for example, (A+B)/(A+B+C+D)).
