Question: In a scenario where a set is defined as {x | x is an integer and x > 0}, which of the following is a valid operation on this set?

Options:

Correct Answer: Finding the intersection with the set of all positive integers.

Solution:

Finding the intersection with the set of all positive integers will still yield the original set, as all elements are positive.

In a scenario where a set is defined as {x | x is an integer and x > 0}, which of the following is a valid operation on this set?

In a scenario where a set is defined as {x | x is an integer and x > 0}, which of the following is a valid operation on this set?

Step 1: Understand the set definition. The set is defined as {x | x is an integer and x > 0}. This means it includes all positive integers (1, 2, 3, ...).
Step 2: Identify the operation to perform. We are looking for a valid operation on this set, such as finding the intersection with another set.
Step 3: Define the second set. The second set is the set of all positive integers, which is also {y | y is an integer and y > 0}.
Step 4: Perform the intersection operation. The intersection of the two sets is the set of elements that are in both sets.
Step 5: Analyze the intersection. Since both sets contain the same elements (all positive integers), the intersection will yield the original set {x | x is an integer and x > 0}.
Step 6: Conclude that the operation is valid. Finding the intersection with the set of all positive integers does not change the original set.
