### why isn't here "multiply"?

why isn't here "multiply"? can you explain it please?

### In this lesson, we're looking

In this lesson, we're looking at the technique of Listing & Counting, in which we simply list all possible outcomes and them count those outcomes.

So, there aren't any sophisticated counting techniques involved here (like using the Fundamental Counting Principle, which involves multiplication)

### can you please explain how

can you please explain how can we solve same question, using fundamental counting principle?

### There's no way to solve this

There's no way to solve this question using the fundamental counting principle, unless we consider a crazy number of cases. The purpose of the question is to show the utility of listing and counting.

### I have one more question,

I have one more question,

how many 3 digit number can be formed so that addition of 3 digit will yield 6. choose any digit out of 0,1,2,3,4,5,6.

### That question requires us to

That question requires us to use a technique known as partitioning, which is beyond the scope of the GRE.

### Thanks for saying that this

Thanks for saying that this would never be on the GRE. It's true.

### Why is (0, 0, 6) not a

Why is (0, 0, 6) not a possibility? Or even (0, 6, 0)?

### Those outcomes are in the

Those outcomes are in the solution. See 2:10 in video.
