s three coats of paint the smaller room requires only two coats of paint. Then the client decided not to paint the smaller room after all.

The total number of gallons of paint needed for the big room is 3x and the number of gallons of paint needed for the small room is 2y. 
                                   3x + 2y = 16
Given the sizes of the room, the relation should be that,
                                    x = 2y
Solving the equation,
                                      3(2y) + 2y = 16
                                               y = 2
Therefore x is equal to 4 gallons. 
With the condition that only the bigger room is painted, the number of gallons of paint used should be 12 gallons and what is left should be 4 gallons.

Well I don't know ! 
Let's take a look and see:

The idea is that there could be more than one way
for a roll of the dice to land with the same number.  

-- If the sum is from 1-4, you get the point.
There are  6  different ways for a roll of the dice to come up 1-4.

-- If the sum is from 5-8, Adam gets the point.
There are  20  different ways for a roll of the dice to come up 5-8.

-- If the sum is 9-12, Lana gets the point.
There are  10  different ways for a roll of the dice to come up 9-12.

-- The game is not fair to all three of you.
-- Lana has a distinct advantage over you.
-- Adam has a big advantage over Lana.
-- Adam has an even bigger advantage over you.
-- You are at a big disadvantage.  (Notice that one of your
numbers ... 1 ... can never come up unless one of the dice
falls off of the table.)
