A look into empirical probability definition and examples

Also known as posterior probability, the basic empirical probability definition states that it is basically a type of probability that focuses on some events taking place, all of which are calculated with the help of empirical evidence that has already been collected. In any given probability distribution, empirical probability is associates with the relative frequency. Basically, in this particular statistical model, the chances of a particular event taking place gains support with the help of market data. On the whole, its calculations are expressed in the form of a ratio that is placed in between the number of times that an event takes place and the number of possible times that it might take place.

What is the empirical probability formula?

In case we are expecting an event given the name E to take place, and P (E) is the probability of its overall outcomes, then:
empirical probability formula

All in all, when you define empirical probability, you would find that it is an estimate which defines the number of times that an event might take place on the basis of how frequently the event occurs once the data has been collected. It is particularly based over direct experiences or observations.

A few empirical probability example

In order to understand the concepts associated with empirical probability in a better manner, it is highly recommended for you to check out a few empirical probability examples. Here is the first empirical probability example for you to consider:

1. Consider that a survey has been carried out where in you need to determine the favourite breeds of dogs of various students. Every student is allowed to choose just a single breed.















Now, what is the probability that the favourite dog of all the students is a Lab?

The answer to this question is very simple. Considering that 35 out of a full 85 students chose a Lab, the probability as per the basic probability formula will be:

This means: 35/85 and the answer to this question is 7/17.
