Working with axiomatic probability.

I am doing a course in discrete mathematics. One of the topics that our course touches upon is probability. Our syllabus doesn't require us to learn a lot of theory, that is to say that we use intuitive notions to solve most problems. As I was reading about probability on the internet I came across the axiomatic approach to probability which sounded very interesting. So I read quite a bit about it. What I am now trying to do is trying to solve homework problems using this approach to see if I truly understand what the axioms say and now I am stuck.

Problem: Consider a box which contains 44 white , 55 blue balls. What is the probability of drawing a white ball and a blue ball in some order if two balls are drawn given that each ball has an equal likelihood of being drawn?

I think I first have to understand what the experiment is.

Experiment: There are 4 white balls and 5 blue balls in a box. Two of these balls will be picked up randomly.

1. What is the sample space?

I think it should be:
