Relative Frequency

The Relative Frequency of an event is the number of times a value occurs as a fraction of the full set.

Example

$200$ seats in a library and $50$ are full

Relative Frequency is $\frac{50}{200}$ = $\frac{1}{4}$

Formula

The Relative Frequency of the event $A$ in $n$ repetitions is defined as:

$f_n(A)=\frac{n(A)}{n}$

Where:

• $n(A)$ is the number of outcomes
