Derivation of conditional probability formula
WebFeb 6, 2024 · Next, we apply Bayes' Rule to find the desired conditional probability: P ( B 1 A) = P ( A B 1) P ( B 1) P ( A) = ( 0.9) ( 0.0001) 0.0010899 ≈ 0.08 This implies that only about 8% of patients that test positive under this particular test actually have kidney cancer, which is not very good.
