Answer 1

Frequency is related to the number of times a value of the data occurs.

Relative frequency is the proportion this value occurs in the set of the total number of outcomes, it can be calculated as:

`\begin{gathered} RF=\frac{Frequency}{Total\text{ number of values}} \\ \text{For example:} \\ RF=(5)/(20)=0.25 \\ RF=(1)/(20)=0.05 \\ RF=(9)/(20)=0.45 \end{gathered}`

The frequency table will be:
