Wo urns contain white balls and yellow balls. The first urn contains 2 white balls and 7 yellow balls and the second urn contains 3 white balls and 10 yellow balls. A ball is drawn at random from each urn. What is the probability that both balls are white?

Base on the question which ask to calculate the probability that both balls are white, and base on the question and in my further calculation, I would say that the answer would be 36.36%. I hope you are satisfied with my answer and feel free to ask for more if you have questions and further claifications
