  1. {1, 2, 3, 4, 5}

  3. {3, 4}
  4. {1, 2, 4, 5}

Questions & Step-by-Step Solutions

If set X contains {1, 2, 3} and set Y contains {3, 4, 5}, what is the hybrid set formed by the union of set X and set Y?
  • Step 1: Identify the elements in set X, which are {1, 2, 3}.
  • Step 2: Identify the elements in set Y, which are {3, 4, 5}.
  • Step 3: Combine all the elements from both sets, starting with set X: {1, 2, 3}.
  • Step 4: Add the elements from set Y to the combined set, but only include unique elements. Set Y has 3, 4, 5.
  • Step 5: Since 3 is already in the combined set from set X, we only add 4 and 5.
  • Step 6: The final hybrid set includes all unique elements: {1, 2, 3, 4, 5}.
  • Set Theory – Understanding the union of two sets, which combines all unique elements from both sets.
