Question 469948
Following are two boxes containing colored and white balls.  A ball is drawn at random from box 1. Then a ball is drawn at random from  box 2, and the colors of balls from both boxes are recorded in order.  Find each of the following:
--------
Box 1: 2 Black  Balls  3White Balls.   
Box 2: 4 Black Balls 2 White Balls.
----------

a. The probability of two white balls::(3/5)(2/6) = 1/5
---------------------------
b. The probability of at least one colored ball::: 1-[1/5] = 4/5
---------------------------
c. The probability of at most one colored ball:: 
P(0 or 1 colored ball) = 1-P(2 colored) = 1-(2/5)(4/6) = 1-(8/30) = 22/30
= 11/15
-----------------------------
d. The probability of colored ball white ball or white ball colored ball
(2/5)(2/6) + (3/5)(4/6) = 16/30 = 8/15
