<PRE><B>Question 1050658</B>
23 marbles: 9 red marbles, 8 white marbles, and 6 blue marbles
Draw two, w/o replacement
a) The probability that the first marble is red and the second is white.
P = (9/23)(8/22)
b) The probability that both are the same color. 
P = 2R + 2W + 2B
P = (9/23)(8/22) + (8/23)(7/22) + (6/23)(5/22)
c) The probability that the second marble is blue.
P = (17/23)(6/22) + 2B (Need to consider both are Blue)
P = .202 + (6/23)(5/22) = .202 + .059 = .261</PRE>
