  6. Intersection Example & Definition The set of all elements that are in common between 2 or more sets U = {1,…,12} X = {1,2,3,4,5,6} Y = {3,4,7,8,11} Z = {4,5,6,9,10,11} X Y Z = {4}

  7. Union Example & Definition U = {alphabet} A = {a,b,c,d,e} B = {vowels} A B = {a,b,c,d,e,i,o,u} The set containing ALL of the elements of 2 or more sets.
