{20,21,30,31}∩{1,2,3}

Solution

1. Identify the elements of set A which are 20, 21, 30, 31$.

2. Identify the elements of set B which are 1, 2, 3$.

3. Compare the elements of both sets to find any common values that appear in both A and B

4. Determine that there are no common elements between the two sets.
