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 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.
