Questions & Step-by-Step Solutions

If set A contains the numbers {1, 2, 3, 4, 5} and set B contains the numbers {4, 5, 6, 7, 8}, what is the intersection of sets A and B?
  • Step 1: Identify the elements in set A. Set A contains the numbers {1, 2, 3, 4, 5}.
  • Step 2: Identify the elements in set B. Set B contains the numbers {4, 5, 6, 7, 8}.
  • Step 3: Look for common elements in both sets A and B.
  • Step 4: The common elements are 4 and 5.
  • Step 5: Write down the common elements as a new set. The intersection of sets A and B is {4, 5}.
  • Set Theory – Understanding the intersection of two sets, which includes elements that are present in both sets.
