How many possible outcomes are there for this?

Question

I am providing a "decision tree" for my website developer - as he builds a "calculator" on our site. If there are 3 questions, with these number of possible answers for each question - how many possible final outcomes could there be?

 

1st question 1 possible answer - 2nd question, 3 possible answers - 3rd question, 3 possible answers.

 

Each question can choose multiple of the possible answers. (ie. 2nd question, can choose 1, ANY 2, or ALL 3 answers - same for 3rd question)

 

I've put together what I think is a "complete tree," but want to be sure that I'm not missing possible outcomes. Thank you!

Answer 1

If you have stated the problem correctly, there is only one way to answer the first question (I'm not sure that is what you meant to write) and there are 7 ways to answer each of the 2nd and 3rd questions (excluding the possibility of choosing none of the possible answers).  This means you have 49 possible end results.
