Question

Observe the venn diagram and
write the given sets.
​

Answer 1

Answer :

A = { 1 , 2 , 3 , 5 , 7 }

B = { 1 , 5 , 8 , 9 , 10 }

A ∩ B = { 1 , 5 }

A U B = { 1 , 2 , 3 , 5 , 7 , 8 , 9 , 10 }

Note :

★ 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 .
