Missed what?

I will post another problem in here.

They missed your post.

I am looking forward to the problem.

**A game is played. You roll a red die and then roll as many green die as the number on the red die. What is the probability of the sum of the green die equalling 17?**

**Is this a generating function problem?**

My first guess would be a no,but I will have to look at it a little.

Maybe the coeff of x**17 in ((x+x**2+x**3+x**4+x**5+x**6)+ (x+x**2+x**3+x**4+x**5+x**6)**2+(x+x**2+x**3+x**4+x**5+x**6)**3+ (x+x**2+x**3+x**4+x**5+x**6)**4+(x+x**2+x**3+x**4+x**5+x**6)**5+ (x+x**2+x**3+x**4+x**5+x**6)**6)/6?

That is almost correct except there is an error. Do you see it?

Oh,yeah,I wasn't really sure about that division by six. Thinking about it again it seems logical not to include it.

Without that 6 down there we would have a combinatorics problem but this is a probability problem.

Well,I need to divide by what we get when we sub x=1.

But as it stands with or without that 6 the answer is not correct.

We have not even established the need for one but that one is not right.

Anything besides mulirplying by a constant?

I would think that multiplying by any constant would not fix it. But that is another question.

Do you have access to a CAS right now?

Not right now. Phone.

Maybe I could try getting on my laptop,but that doesn't seem probable. At least not till 10.

Remember any answer is not any good unless it is arrived at in two different ways. Two different directions, then you have some certainty.

I know of a forum filled with olympiad hopefuls. They try to solve combinatoric problems. They post the wrong answer, why? Because they did not check it to see if it was possibly correct. Computers and combinatorics are married. When you use them together you will be more accurate than those who do not.

I think if you would have expanded that gf you would have seen that it can not be right. We would not be going back and forth right now. In short, we would be going faster.

I just had an idea! Should those be EGFs instead of OGFs?

Does order count? Is 5 + 3 + 2 different than 3 + 5 + 2?

Nope. Isn't that why it should be an EGF?
