Question

A = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}; B = {2, 3, 5, 7}. Find A ∩ B and show that A ∩ B = B.

Answer 1

hey dear
here is your answer ✌ ✌

============
here,
A= {1,2,3,4,5,6,7,8,9,10}
B= { 2,3,5,7}

A n B means those elements which are present in set A as well as in set B, So

AnB = {2,3,5,7}

which is equal to set B.

hence AnB = B

hope it helped ^_^
