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}
