To find the probability that a senior citizen takes either blood pressure-lowering or cholesterol-lowering medication, we use the formula for the probability of the union of two events: P(A or B) = P(A) + P(B) - P(A and B). Here, P(A) = 0.57 (blood pressure-lowering medication), P(B) = 0.40 (cholesterol-lowering medication), and P(A and B) = 0.03 (both medications). Substituting these values, we get 0.57 + 0.40 - 0.03 = 0.94.
