Answer:
intersection is { } or ∅
Step-by-step explanation:
A ∩ B, is the set containing all elements of A that also belong to B.
Here first set { 6, 8 , 10, . . . 20} Set of even number from 6 to 20
Second set { 1, 3 , 5 , 7} Set of odd numbers from 1 to 7
There is no common elements in the set.
Therefore intersection of the set is empty or null set.
