<PRE><B>Question 450022</B>
Two urns contain white balls and yellow balls. 
The 1st urn contains 5 white balls and 8 yellow balls and 
the 2nd urn contains 9white balls. and 2 yellow balls 
A ball is drawn at random from each urn. 
What is the probability that both balls are white.
----
The events are independent:
----
P(white1 and white2) = P(white1)*P(white2) = (5/13)(9/11) = 45/141
