The probability that a given urine sample analyzed in a pathology lab contains protein is 0.73 (event A). The probability that the urine sample contains the protein albumin is 0.58 (event B). The probability that a sample contains protein, given that albumin is detected, is 1. Which statement is true?
a. Events A and B are dependent because P(A|B) =P(A).
b. Events A and B are dependent because P(A| B) ≠ P(B).
c. Events A and B are dependent because P(A|B) = P(A) + P(B).
d. Events A and B are dependent because P(A| B)≠ P(A).
e.Events A and B are dependent because P(A|B) = P(A).

Answers

The right answer for the question that is being asked and shown above is that: "e.Events A and B are dependent because P(A|B) = P(A)." The probability that a sample contains protein, given that albumin is detected, is 1. The statement that is true is this events A and B are dependent because P(A|B) = P(A).
