here i check option---> i let P = probability, P and Q is replaced by A and B.
A) it is saying independent means P(A ^ B) = P(A)* P(B) so option A is false
B) P(AÜ B) = P(A) + P(B) - P(A ^ B)
hence P(AÜ B) >= P(A) + P(B) its false option B is false
C) if A and B is mutually exclusive means P(A ^ B) = 0 then its independent ........its false there is no relation independent and mutually exclusive
D) P(A^ B) <= P(A)
its true
hence option D is correct
