A die is rolled and showing any number is directly proportional to that number. If prime number appears then a ball is chosen from urn `A` containing 2 white and 3 black balls otherwise a ball is chosen from urn `B` containing 3 white and 2 black balls Then.
The probability of drawing a black ball is
