Questions & Step-by-Step Solutions

If set A = {x | x is an even number less than 10} and set B = {x | x is a prime number less than 10}, what is A ∩ B?
  • Step 1: Identify the elements of set A. Set A includes all even numbers less than 10. The even numbers less than 10 are {0, 2, 4, 6, 8}.
  • Step 2: Identify the elements of set B. Set B includes all prime numbers less than 10. The prime numbers less than 10 are {2, 3, 5, 7}.
  • Step 3: Find the intersection of sets A and B. The intersection A ∩ B includes elements that are in both set A and set B.
  • Step 4: Compare the elements of set A and set B. The only number that is both even (from set A) and prime (from set B) is 2.
  • Step 5: Write the intersection. Therefore, A ∩ B = {2}.
