Question
he dot plots show the number of students who play each sport in a classroom. Which data representation shows a non-uniform probability?
Three dot plots of sports. Plot A has 7 dots on volleyball, 7 dots on baseball, 7 dots on track, 7 dots on softball, and 7 dots on football. Plot B has 6 dots on volleyball, 6 dots on baseball, 6 dots on track, 6 dots on softball, and 6 dots on football. Plot C has 4 dots on volleyball, 4 dots on baseball, 4 dots on track, 4 dots on softball, and 4 dots on football.

To determine which data representation shows a non-uniform probability, we need to look at how many students play each sport in the classrooms represented by the dot plots.
- **Plot A**: 7 dots for volleyball, 7 dots for baseball, 7 dots for track, 7 dots for softball, and 7 dots for football. (Uniform distribution as all sports have the same number of players)
- **Plot B**: 6 dots for volleyball, 6 dots for baseball, 6 dots for track, 6 dots for softball, and 6 dots for football. (Uniform distribution as all sports have the same number of players)
- **Plot C**: 4 dots for volleyball, 4 dots for baseball, 4 dots for track, 4 dots for softball, and 4 dots for football. (Uniform distribution as all sports have the same number of players)
In all cases above, all sports have an equal number of participants, which means they represent a uniform probability distribution.
Since none of the plots shows a non-uniform probability (where the number of students playing different sports would vary), the answer is:
**None of these.**
