The symmetric difference of A and B, denoted

Answered question


The symmetric difference of A and B, denoted by A B, is the set containing those elements in 
either A or B, but not in both A and B.
a) Find the symmetric difference o f { 1, 3 , 5 } and { 1, 2, 3 } .
b) Determine whether the symmetric difference is associative; that is, if A, B, and C are sets, does it follow that
A (B C) = (A B) C?

Given: A={ 1, 3 , 5 } and B={ 1, 2, 3 }


The formula of symmetric difference of two sets:



{1,3,5}{1,2,3}={1,2,3,5} and




Hence, A-B={x|xA but xB}
