Question

Which of the following formulae is used to determine the experimental probability of an event?
Number of favorable outcomesTotal number of possible outcomes
The number of times the event occursThe total number of trials
Number of favorable outcomesNumber of unfavorable outcomes
Number of unfavorable outcomesNumber of favorable outcomes

Answer 1

The formula used to determine the experimental probability of an event is:

\[
\text{Experimental Probability} = \frac{\text{The number of times the event occurs}}{\text{The total number of trials}}
\]

So, the correct choice from your options is:

**The number of times the event occurs / The total number of trials.**
