Case 1:
No: of white balls = 2

No: of black balls = 4

Total no: of balls = 6

Probability of white balls transferred = 2/6 = 1/3

total no. balks in urn A is 6
white balls in urn A are 2
black balls in urn A are 4

total no. of balls in urn B is 12
white balls in urn B are 5
black balls in urn B are 7

total no. of ways to transfer a ball from urn A to B are 6
no. of ways in which a white ball can be drawn is 2.
therefore the probabiliy of transferring the white ball is 2/6 i.e. 1/3

hope this helps:p
