Answer:
According to the question we have 3 cases
1) BB
2) WW
3) BW
After putting a white ball in an urn we get
BBW
WWW
BWW
The probability that the white ball is drawn = 1/3
The probability that the drawn ball is white from second case = 3/3 = 1
The probability that the drawn ball is white from teh third case = 2/3
As all the three cases are independent.
Required probability = 1/3 × 1 × 2/3 = 2/9
