Answer
Approximately 1 or 100%.
Work Step by Step
We can get the variation of a frequency distribution by a relative frequency distribution. In this, each class gets replaced by a relative frequency that we can calculate in the following way: $relative \ frequency \ of \ a \ class=\frac{frequency \ of \ the \ class}{sum \ of \ all \ frequencies}$. Here, the sum of relative frequencies should be approximately 1 or 100%.
