<PRE><B>Question 128511</B>
A bag contains five balls numbered 0 through 4. Two balls are chosen at random in succession. The first ball is replaced before the second is chosen.
a. How many outcomes are possible.
----------------------------
Since the 1st ball is replaced,
there are 5 ways to choose the 1st ball
there are 5 ways to choose the 2nd ball
--------------
The total # of outcome pairs is 5*5 = 25
