Question

Find A ∪ B, A ∩ B, A – B and B – A for the following sets

A = {a, b, c, e, u} and B = {a, e, i, o, u}

Answer 1

A = {a, b, c, e, u} and B = {a, e, i, o, u}

A ∪ B = {a, b, c, e, u) ∪ {a, e, i, o, u)

= {a, b, c, e, i, o, u}

A ∩ B = {a, b, c, e, u} ∩ {a, e, i, o, u}

= {a, e, u}

A – B = {a, b, c, e, u) – {a, e, i, o, u)

= {b, c}

B – A = {a, e, i, o, u} – {a, b, c, e, u}

= {i, o}
