Question

f A = {1, 3, 5, 7, 9} and B = {2, 3, 5, 7} , then what is A ∩ B ? *

Answer 1

Answer:

A={1,3,5,7,9 }

B={2,3,5,7}

A intersection B = {3,5,7}

Answer 2

A = { 1,3,5,7,9 }

B = { 2,3,5,7 }

then , A ∩ B ( A intersection B ) means the elements that are present in both set A as well as in set B .

so , A ∩ B = { 3,5,7 }
