1. **State the problem:** We want to find the probability that a randomly selected person from the survey walks daily.
2. **Identify the data:** From the table:
- Walk Daily and Have a Dog: 78
- Walk Daily and Do Not Have a Dog: 52
- Do Not Walk Daily and Have a Dog: 43
- Do Not Walk Daily and Do Not Have a Dog: 62
3. **Calculate total number of participants:**
$$78 + 52 + 43 + 62 = 235$$
4. **Calculate total number of people who walk daily:**
$$78 + 52 = 130$$
5. **Use the probability formula:**
$$P(\text{Walk Daily}) = \frac{\text{Number who walk daily}}{\text{Total number of participants}} = \frac{130}{235}$$
6. **Simplify the fraction:**
$$\frac{130}{235} = \frac{\cancel{5} \times 26}{\cancel{5} \times 47} = \frac{26}{47}$$
7. **Final answer:**
The probability that a randomly selected person walks daily is
$$\boxed{\frac{26}{47}}$$
