# Experimental probability

**Expected probabilities**

Expected probabilities is can include the following examples:

- The possibility of getting a head when flipping a coin is and if flipped 50 times will be 50 x = 25 times.
- However, the reality is that this is an estimate and not exact.

**Relative frequency**

Relative frequency on the other hand is the fraction of the actual number of times the event occurs. There in the example below, a dice is thrown a number of times to work out the probability of the actual outcome:

Point to note

- This situation can also be called the
**experimental probabilities**.

**Experimental and theoretical probability**

- Experimental probability – calculating the probability though experimentation and the collection of data, this may well vary each time it is conducted.
- Theoretical probability – calculating the probability of the event based on the actual assumptions. For example, a dice has only 6 sides therefore it can only have a change of landing any number.
