Answer :
Since in the history of track and field no woman has broken the 10 second barrier in the 100 meter run, we have a total of 0 people that broke the achievment among all people that tried to break it.
Since the empirical probability is calculated with these real values, let's use the variable x to represent the number of people that tried to break that achievment, so we have:
[tex]\begin{gathered} \text{Empirical probability}=\frac{\text{ number of people that broke the achievment}}{\text{ total number of people that tried}} \\ \text{Empirical probability}=\frac{0}{x} \\ \text{ Empirical probability}=0 \end{gathered}[/tex]So the empirical probability of a woman breaking the 10 second barrier next year is 0%.
