Given two events, A and B, of a random experiment, with probabilities such that $p ( A ) = \frac { 4 } { 9 } , \quad p ( B ) = \frac { 1 } { 2 } y p ( A \cup B ) = \frac { 2 } { 3 }$, it is requested:\ a) (1 point) Check whether events A and B are independent or not.\ b) (1 point) Calculate $p ( \bar { A } / B )$, where $\bar { A }$ denotes the complementary event of A .
