Suppose that in the human population gene A occurs in 25% of people, gene B occurs in 44% of people, and genes A and B occur together in 11% of people. Are genes A and B independent? Mathematically justify your answer. Please help me with this problem. The question wants you to decide whether or not the situation is independent by proving: I understand that P(A) = 25 and P(B) = 44 but I do not know how to get the . Thanks in advance.
