Answer:
4/5 is the probability of white ball from urn 2
Step-by-step explanation:
Correct statement of the question is ;
Urn 1 contains two white balls and one black ball, while urn 2 contains one white bait and five black balls. One ball is drawn at random from urn 1 and placed in urn 2. A ball is then drawn from urn 2. It happens to be white. What is the probability that the transferred ball was white?
We solve it ;
Probability of taking out balls from urn 1
<u>a) for white ball</u>
<u>b) for balck ball</u>
If one ball is taken from urn 1 and put in urn 2 (which readily contains one white and five black balls)
Probability of taking out balls from urn 2
<u>a) for white ball</u>
Then the probability that white ball was transferred from urn 1 to urn 2 is;
So, the probability that white ball is drawn from urn 2 is 4/5
