Answer:
The intersection in them is {1, 7}
Step-by-step explanation:
Let us revise some definition in the operation of sets of numbers
- The intersection of two sets of numbers is the set of all elements belong to both sets
- The union of two sets of numbers is the set of all elements belong to one of the two sets (without repetition)
→ Ex: set A = {1, 2, 3, 5, 6} and set B = {4, 5}, then
- A ∩ B = {5} ⇒ ∩ is the symbole of intersection
- A ∪ B = {1, 2, 3, 4, 5, 6} ⇒ ∪ is the symbole of union
Let us solve the problem
∵ C = {0, 1, 3, 5, 7} , D = {1, 2, 4, 6, 7}
→ The common elements in the two sets are 1 and 7
∴ C ∩ D = {1, 7}
∴ The intersection in them is {1, 7}
