Final answer:
If a set has zero content, its complement also has zero content.
Step-by-step explanation:
To prove that if s has zero content, then s' has zero content, we need to understand the concept of content in mathematics. The content of a set is essentially its measure or size. If s has zero content, it means that it is an empty set or that it contains no elements. Now, let's consider the complement of s, denoted as s'. The complement of a set contains all the elements not in the original set. Since s is empty and contains no elements, its complement s' would contain all elements. Therefore, s' has zero content.
