Let S = {1,2,3,...,18,19,20} be the universal set.

Let sets A and B be subsets of S, where:

Set `A = \{2,4,7,8,11,13,16,19,20}`

Set `B = \{2,3,6,10,11,15,16}`

LIST the elements in Set A and Set B: { }

LIST the elements in Set A or Set B: { }

Enter the elements as a list, separated by commas. If the result is the empty set, enter DNE
