1. The problem asks to define the sample space for a given experiment. 2. The sample space is the set of all possible outcomes of an experiment. 3. For example, if the experiment is tossing a fair coin once, the sample space is $S = \{\text{Heads}, \text{Tails}\}$. 4. If the experiment is rolling a six-sided die, the sample space is $S = \{1, 2, 3, 4, 5, 6\}$. 5. To share the sample space, you list all possible outcomes clearly and completely. 6. Without a specific experiment given, the sample space cannot be precisely defined, but the concept remains the same: list all possible outcomes.
