Step 1
A conditional relative frequency is a frequency that compares the frequency count to the marginal total that represents the condition. This table gives the information regarding how many members of a group have that particular characteristic.
To find conditional relative frequency formula is, Number of items with particular characteristics divided by a total number of items.
Step 2
Divide the number of girls who prefer baseball with the total number of girls. Express the answer in the form of a percentage.
The number of girls who play baseball =14
Total number of girls =60
=1460×100=23.33%
Correct answer: option C
