How is the relative frequency of an event worked out?
AOccurrences over event size
BTotal trials over occurrences
CEvent size over total trials
DOccurrences over total trials
Answer & Solution
Correct answer: D. Occurrences over total trials
1. Relative frequency is an experimental quantity rather than a theoretical one.
2. You repeat the experiment many times and count how often the outcome falls in the event set.
3. That count is then divided by the total number of trials conducted.
4. Because it is experimental, repeating the whole run can give a different value each time.
