Answer:
Answer to 6 = 26
Answer to 7 = 10
Step-by-step explanation:
Givens
Sofas = 3
Tables = 4
Rugs = 2
Formula
I don't think there is a formula for this. You can only list the possibilites I think.
Solution
Rugs and Sofas: are chosen. Rugs * Sofa = 2 * 3 = 6
Rugs and Tables, are chosen. Rugs*Tables = 2 *4 = 8
Tables and Sofas are chosen. Tables*Sofas = 4*3 = 12
Total number of ways of choosing 2of 3 = 26
Again, I don't see any other way of doing this than by listing the possibilities.
Solution
The most any one person can get is 4. The other two get 1 each.
411
141
114 Total 3
Then the next possibility is one person gets 3 and the other 2 get one or two each.
321
312
132
123
231
213 Total 6
Now we can have 222
So the total number of ways is 10
