What is a relative frequency?

The relative frequency of an event is the proportion of the total no. of a result under which a defined event occurred with respect to the whole actual event.

So, from the given table:

• Roller staking is more popular because it has a higher amount of results.

$\mathbf{\implies \dfrac{x}{100}\times 0.20 = 0.14}$

$\mathbf{\implies0.20x = 14}$

$\mathbf{\implies x = 70\%}$

• The percentage of 8th graders that want to go to the water is 70%
