Final answer:
Empirical probability is obtained by dividing the number of successful trials by the total number of trials. It's an observation-based measure that reflects real-world occurrences. Therefore correct option is C
Step-by-step explanation:
By definition, empirical probability is calculated by dividing the number of times the event occurs (number of successful trials) by the total number of opportunities for the event to occur (total number of trials). Therefore, the correct answer is:
- Number of successful trials
___________________________
Total number of trials
As an example, if we observe that we get a 'head' 25 times out of 100 coin tosses, the empirical probability of getting a 'head' would be 25/100 or 0.25.
Empirical probabilities are based on the observation and recording of actual outcomes, as opposed to theoretical probabilities which are based on expected outcomes.
Moreover, empirical probability is particularly useful when dealing with large data sets where outcomes can be recorded and analyzed.
