To find the sample space, we can list all possible pairs of outcomes. For example, the first choice could be blue and the second choice could be blue, or the first choice could be blue and the second choice could be orange, and so on.
The sample space for this experiment is:
{(blue, blue), (blue, orange), (blue, white), (orange, blue), (orange, orange), (orange, white), (white, blue), (white, orange), (white, white)}
Therefore, there are 9 possible outcomes in the sample space.
