Answer:
A ∪ B = {2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13}
A ∩ B = {5}
Step-by-step explanation:
A ∪ B means all the elements in sets A and B without repetition
A ∩ B means the common elements in the two sets A and B
∵ Set A = {5, 6, 7, 8, 9, 10}
∵ Set B = {2, 3, 4, 5, 11, 12, 13}
→ To Find A ∪ B, write all the elements in the two sets but don't
repeat the common element
∵ 5 is a common element in the two sets
∴ Don't repeat it in A ∪ B
∴ A ∪ B = {2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13}
→ To find A ∩ B, write the common elements in the two sets
∵ 5 is the only common element in the two sets
∴ A ∩ B = {5}
