Q7 of 162 Page 1

Mark the correct alternative in the following:

The symmetric difference of A = {1, 2, 3} and B = {3, 4, 5} is


Here,A={1,2,3} and B={3,4,5}


A∖B={1,2,3}∖{3,4,5}


={1,2,3}∖{3}


={1,2}


B∖A={3,4,5}∖{1,2,3,4}


={3,4,5}∖{3}


={4,5}


AΔB=(A∖B)⋃(B∖A)


={1,2}⋃{4,5}


={1,2,4,5}
