Answer:
C ∪ D = {2, 3, 4, 5, 8, 9, 10, 11}
Step-by-step explanation:
A={x | x is an even integer}
B={x | x is an odd integer},
C={2, 3, 4, 5},
D={8, 9, 10, 11}.
A union of two or more sets is the collection of the members of the sets in a set without repeating any element.
Given sets C and D above, the union of the two sets is the set:
C ∪ D = {2, 3, 4, 5, 8, 9, 10, 11}
Note: The Intersection is the collection of sets that are common to C and D. in this case no element is common, therefore the intersection is a Null Set.
