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 .
