The experiment is to toss two balls into four boxes in such a way that each ball is equally likely to fall in any box. Let X denote the number of balls in the first box.

2. Relevant equations

What is the cumulative distribution function of X?

3. The attempt at a solution

I have enumerated what I suppose to be included in the sample space as follows: {(bb, 0, 0, 0), ((b, b, 0, 0), (b, 0, b, 0), (b, 0, 0, b), (0, bb, 0, 0), (0, b, b, 0), (0, b, 0, b), (0, 0, bb, 0), (0, 0, b, b), (0, 0, 0, bb)}

b stands for the box having a ball, bb stands for the box having the two balls, 0 for the box having no ball

I honestly don't know what to do next. Can some please guide me answering the problem?
