       A		B		


       P(A=1) = p	P(B=1) = p
       P(A=0) = 1-p	P(B=0) = 1-p			


       P(A=1,C=1) = P(A=1) . P(C=1) = p.{P(A=1,B=0)+P(A=0,B=1) = 2.p^2.(1-p)		(1)
       P(A=1,B=0) = P(A=1) . P(B=0) = p.(1-p)		                 		(2)

Since, (1) & (2) are not equal to each other, A & C are not independent of each other when bits are biased.
