Question

if A = {1,2,3,3} and B = {1,2,3,4,5,6} , then find the A ⌒ B and B ⌒ A . are they equal

Answer 1

Answer:

Given A = {1,2,3} , B ={1,2,3,4,5,6}

A intersection B= {1,2,3} intersection {1,2,3,4,5,6}

={1,2,3}

B intersection A={1,2,3,4,5,6} intersection {1,2,3}

={1,2,3}

Therefore A intersection B and B intersection A are equal
