Solution
- The formula for the relative frequency of an event is:
[tex]\begin{gathered} rf=\frac{f}{n} \\ where, \\ f=\text{ the number of times an event occurred in the observation} \\ n=\text{ the total frequencies} \end{gathered}[/tex]
- The number of times that 1 occurs in the dataset is 8 times.
- Thus, the number of times the event of spinning a "1" is 8. i.e. f = 8.
- We are told that the spinning takes place 21 times. Thus, n = 21.
- Therefore, the relative frequency of spinning the number 1 is:
[tex]rf=\frac{8}{21}[/tex]
