Enter the number of times an event occurred and the number of times the experiment was performed to calculate the empirical probability.
Empirical Probability Formula
The following formula is used to calculate an empirical probability.
EP = #O / #E
- Where EP is the empirical probability
- #O is the number of times an event occurred
- #E is the number of times the experiment was performed
Empirical Probability Definition
An empirical probability is the chance that an event occurs during a given empirical experiment.
Empirical Probability Example
How to calculate empirical probability?
- First, determine the number of time the experiment is performed.
For this example we will say the experiment or test was performed 10 times.
- Next, determine the number of events.
Measure the number of positive or successful outcomes occurred during those 10 experiments. We will say that there were 5 events.
- Finally, calculate the empirical probability.
Using the formula we find the probability to be 5/10 = .5 = 50%.
Empirical probability is just normal probability but applied to empirical situations, such as science experiments.
