The numbers 1, 2, 3 and 4 are written separately on four slips of paper. The slips are put in a box and mixed thoroughly. A person draws two slips from the box, one after the other, without replacement. Describe the sample space for the experiment.

Explanation

To solve the problem, we need to describe the sample space for the experiment of drawing two slips from a box containing the numbers 1, 2, 3, and 4 without replacement.

### Step-by-Step Solution:

1. **Understanding the Experiment**:
