<PRE><B>Question 1059201</B>
An urn contains 900 balls of which 300 are white, 200 are red, and the rest are blue. 
Note:: There are 400 blue
-------------------------------------
What is the probability that in a random sample of 10 balls from the urn, there are exactly 5 white and exactly 2 blue balls?
------------------------------------
Probability =  (300C5 * 400C2 * 200C3)/900C10 = 0.02246
----------------
