	Balls and cubes in an urn		2008-09-09
		Dave pose la question : In an urn, there are 80 objects of two kinds: cubes (C) and balls (B). An object can be either red (R) or green (G).

Similarly, the number of red objects is not necessarily equal to the number of green objects. Someone tells us that in the urn there are 20 red cubes, 50 balls, and 30 red objects. An object is randomly selected from the urn. (a). What is the probability that a green ball is selected? (b). If we know that a cube has been selected, what is the probability that it's red? (c).
