Question

Find the symmetric difference between the following sets

R = {l, m, n, o, p} and S = {j, l, n, q}

Answer 1

R = {l, m, n, o, p}

S = {j, l, n, q}

R – S = {l, m, n, o, p} – {j, l, n, q}

= {m, o, p}

S – R = {j, l, n, q} – {l, m, n, o, p}

= {j, q}

R ∆ S = (R – S) ∪ (S – R)

= {m, o, p} ∪ {j, q}

= {m, o, p, j, q}
