Question

M={2,3,4,6,7} D={2,4,6} intersection of M and D. union of M and D​

Answer 1

M ∪ D= { 2, 3, 4 , 6 , 7}

M ∩ D= { 2, 4 , 6}

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}
