Answer

Explanation:

Step1: Calculate junior varsity - running percentage

The number of junior varsity swimmers who chose running is 20, and the total number of junior varsity swimmers is 30. The percentage is $\frac{20}{30}\times100%\approx 66.7%$.

Step2: Calculate all - swimmers running percentage

The number of all swimmers who chose running is 28, and the total number of all swimmers is 60. The percentage is $\frac{28}{60}\times 100%\approx 46.7%$.

Step3: Compare the percentages

Since $66.7%>46.7%$, a junior varsity swimmer is more likely to choose running than a swimmer chosen at random.

Answer:

The percentage of junior varsity swimmers who chose running is about $66.7%$. The percentage of all swimmers who chose running is about $46.7%$. So, a junior varsity swimmer would be more likely to choose running than a swimmer chosen at random.
