Answer:
18
Explanation:
Let's label the meat A₁, A₂, and A₃
Vegetables B₁, B₂, and B₃
Desserts C₁ and C₂
Now just make as many ways you can
A₁ B₁ C₁
A₁ B₂ C₁
A₁ B₃ C₁
A₁ B₁ C₂
A₁ B₂ C₂
A₁ B₃ C₂
That's all of the A₁s
Now it's going to be the same fore A₂ and A₃
Since there are 6 in A₁, there'll be 6 in A₂ and 6 in A₃
Now that's 18
The mathematical way would be using the counting principle
So 3*3*2 = 18
