That implies, A and B are independent.
ii)Since A and B are independent, that implies 
and also 
Hence, we can write

The event is said to be repelled by the event B if P(AB) . P (A), and to be attracted by B if P(AIB) > P(A). Show that (a) if B attracts A, then A attracts B, and Bc repels A (Hint: use the definition of conditional probability) (b) If A attracts B, and B attracts C, does A attract C? (Hint: consider when A and C are disjoint sets).
