You can put this solution on YOUR website! due to a manufacturing error, three cans of regular soda were accidentally filled with diet soda and placed into a 12-pack. Suppose that two cans are randomly selected from the 12-pack, determine the probability that both contain regular soda?
------------------------------
# of ways to delect 2 of the 9 regular soda cans: 9C2 = 36 ways
------------------------
# of possible pairs in the 12-pack: 12C2 = 66 pairs
-----------------------------------------
P(2 regular soda) = 36/66 = 6/11
========================
