Sample Space
7.SP.C.7
Definition
The set of all possible outcomes of a probability experiment. Written as S = {}. Each element is one possible outcome.
Examples
- Flip a coin and roll a die: 2 × 6 = 12 total outcomes in the sample space.
- Rolling a single die: S = {1, 2, 3, 4, 5, 6}.
Key rule
The sample space must include every possible outcome — nothing missing, nothing added.
Memory hook
Every single thing that could possibly happen.
