Question

MUN= {1,2,3,4,5,6}
M={1,3,6} THEN WHICH OF THE FOLLOWING REPRESENT N??

Answer 1

Step-by-step explanation:

M U N ={1,2,3,4,5,6}

{1,3,6} U N={1,2,3,4,5,6}

N={2,4,5}

Answer 2

Note :

★ Set : A well defined collection of distinct objects is called a set .

★ Union of two sets : The union of two sets A and B is the set of all those elements which are either in A or in B or in both .

→ This set is denoted by A U B .

★ Intersection of two sets : The intersection of two sets A and B is the set of all those elements which are in common in both A and B .

→ This set is denoted by A ∩ B .

★ Difference of sets : The difference of two sets A and B in the order ( also called relative complement of B in A ) is the set of all those elements of A which are not the elements of B .

→ It is denoted by (A - B) .

Solution :

• Given : MUN = { 1 , 2 , 3 , 4 , 5 , 6} and M = {1,3,6}
• To find : N = ?

We have ;

MUN = { 1 , 2 , 3 , 4 , 5 , 6 } and

M = { 1 , 3 , 6 } .

Thus ,

The set N may be :

• N = { 2 , 4 , 5 }

• N = { 1 , 2 , 4 , 5 }

• N = { 2 , 3 , 4 , 5 }

• N = { 2 , 4 , 5 , 6 }

• N = { 1 , 2 , 3 , 4 , 5 }

• N = { 1 , 2 , 4 , 5 , 6 }

• N = { 2 , 3 , 4 , 5 , 6}

• N = { 1 , 2 , 3 , 4 , 5 , 6 }

→ In all the above cases

MUN = { 1 , 2 , 3 , 4 , 5 , 6 }
