alleryIn a random experiment with sample space S, the event S itself always occurs. Such an event is called:
AAn exhaustive pair
BThe sure event
CA simple event
DThe null event
Answer & Solution
Correct answer: B. The sure event
1. Whatever the outcome, it always lies inside the whole sample space S.
2. An event that is certain to occur on every trial is the sure event.
3. The sample space S therefore describes the sure event.
