1. **State the problem:** We have a survey table of students categorized by gender and their preferred relaxation method: reading or listening to music.
| Gender | Read | Listen to Music |
|--------|------|----------------|
| Female | 87 | 94 |
| Male | 68 | 110 |
We need to find the probability that a randomly selected student who is female relaxes by listening to music.
2. **Formula used:** The conditional probability formula is
$$P(\text{Listen to Music} \mid \text{Female}) = \frac{P(\text{Listen to Music and Female})}{P(\text{Female})}$$
3. **Calculate total females:**
$$\text{Total Females} = 87 + 94 = 181$$
4. **Calculate probability:**
$$P(\text{Listen to Music} \mid \text{Female}) = \frac{94}{181}$$
5. **Simplify fraction if possible:** 94 and 181 have no common factors other than 1, so fraction is already simplified.
6. **Final answer:**
The probability that a randomly selected female student relaxes by listening to music is
$$\boxed{\frac{94}{181} \approx 0.519}\text{ or }51.9\%.$$
