Answer
The symmetric difference is { 2,5}
Work Step by Step
Let's take the set A = { 1,3,5} and set B = { 1,2,3}
The symmetric difference means that it is a set containing elements that are in either A or B but not in both of them.
1 and 3 are elements of both A and B. Only 2 and 5 are elements of either A or B but not both.
