Answer:
M ∪ D= { 2, 3, 4 , 6 , 7}
M ∩ D= { 2, 4 , 6}
Step-by-step explanation:
UNION OF SETS : The union of two sets P and Q is the set of elements which belong in A or in B or in both.
Here, M = {2,3,4,6,7} D = {2,4,6}
⇒ M ∪ D= { 2, 3, 4 , 6 , 7}
INTERSECTION OF SETS : The intersection of two sets P and Q is the set of elements which belong in A and B both.
Here, M = {2,3,4,6,7} D = {2,4,6}
⇒ M ∩ D= { 2, 4 , 6}
