You are told that p(a | b) = p(b | a). which statement below must be true?
a and b are equally likely
p(a | b) = 0.5
a and b are independent
a and b are dependent

The best answer to the question that is being stated above would be that A and B are both dependent. If I was told that P(A | B) = P (B | A), then the true statement is that both variables inside would be dependent upon each other, no matter if you exchange their places with one another.

The answer of the above question is
