<h3>Further explanation</h3>
The probability of an event is defined as the possibility of an event occurring against sample space.
Let us tackle the problem.
If the first urn contains 3 white balls and 6 yellow balls , then the probability of picking up a white ball from the first urn is:
If the second urn contains 7 white balls and 3 yellow balls , then the probability of picking up a white ball from the second urn is:
From the above results , the probability that both balls are white can be calculated using following formula:
