a. $\frac{19}{51}$
b. $\frac{51}{130}$
c. $\frac{65}{130}$
d. $\frac{32}{51}$

Explanation:

Step1: Recall relative - frequency formula

Relative frequency = $\frac{\text{Frequency of the category}}{\text{Total frequency}}$

Step2: Identify relevant values

The frequency of girls who prefer poetry is 51, and the total number of girls surveyed is 130.

Step3: Calculate relative frequency

Relative frequency = $\frac{51}{130}$

Answer:

B. $\frac{51}{130}$
