Answer:

Answer to 6 = 26

Answer to 7 = 10

Step-by-step explanation:

Six

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

Seven

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
