AThe full list of possible outcomes
BThe single most probable outcome
CThe number attached to an outcome
DAny subset of the sample space
Answer & Solution
Correct answer: D. Any subset of the sample space
1. An event is any subset of the sample space, so it may hold one outcome, several, or none at all.
2. Rolling an odd number is an event holding the three outcomes 1, 3 and 5.
3. Because it is a subset, its probability can never exceed the probability of the whole sample space, which is 1.
4. The full list of outcomes is the sample space rather than an event drawn from it.
