122 Section 7.6: Problem 5
(8 points) Suppose that there two urns and are equally likely to be chosen. Um 1 contains 3 white and 2 red balls, and urn 2 has 1 white and 2 red balls.
If a ball is randomly drawn, what is the probability that it came from um 1 given that such a ball is white?
(Hint: You may use:
U_(1) for the event of choosing urn1.
U_(2) for the event of choosing urn2.
W for the event of drawing a white ball.
R for the event of drawing a red ball.
Then draw a tree diagram to find the desired probability value).
R for the event of drawing a red ball. W for the event of drawing a white ball. U1 for the event of choosing urn1.
