`A` and `B` are two events defined as follows:
A:It rains today with`P(A)=40 %`
B: It rains tomorrow with `P(B)=50 %`
Also, `P` (it rains today and tomorrow) `=30 %`
Also, `E_1: P(AnnB)//(AuuB)` and `E_2: P({(Ann barB )or(Bnn barA )}//(AuuB))` . Then which of the following is/are true ?
(a) `A` and `B` are independent events
(b) `P(A//B)`<`P(B//A)`
(c)`E_1` and `E_2` are equiprobable
(d)`P(A/(AuuB))=P(B//(AuuB))`
