Understand the question explain and u will be brainiest

The answer is 1/7
This is because the question asks if a student DOES NOT have any pets, so you find the total outside of the ‘has pets’ area. This is 30 that have siblings and 5 which do not:
30+5 = 35
Then the question asks for the probability that they DO NOT have siblings so that is 5 people.
5/35 = 1/7
