Two marbles are drawn randomly one after the other without replacement from a jar that contains 3 red marbles, 6 white marbles, and 7 yellow marbles. Find the probability of the following events.
(a) A red marble is drawn first followed by a white marble.
The probability is : (3/16)(6/15)
----------------------------------------------
(b) A white marble is drawn first followed by a white marble.
The probability is : (6/16)(5/15)
-------------------------------------------
(c) A yellow marble is not drawn at all.
The probability is : (9C2)/(16C2) = (9/16)(8/15)
