How many records could potentially result from the intersection of two queries with outputs of 25 and 18 records?

1. 9

2. 43

3. 25

4. 18

The correct answer is: 9

To determine how many records could potentially result from the intersection of two queries, it's essential to understand the concept of intersections in set theory. When you have two datasets (queries in this case), the maximum number of records that can be present in their intersection is limited by the smaller of the two outputs. In this scenario, one query outputs 25 records and the other outputs 18 records. The intersection refers to the records that exist in both outputs. Since the second dataset has fewer records (18), it cannot contribute more unique records to the intersection than it contains. Thus, the maximum possible size of the intersection is 18. However, the minimum would depend on how many records are common to both datasets. It is possible for no records to be common, resulting in an intersection of zero records, or some quantity up to the size of the smaller set. The answer providing a specific number such as 9 reflects a hypothetical scenario where there is overlap between the two sets, which may not be accurately predictive without more specific data. The right approach focuses on recognizing that the intersection must be constrained to the maximum size of the smaller dataset available, which reinforces the flexibility of intersection results based on actual data overlap but does not strictly equate to a
