Question

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

A = {2, 6, 10, 14} and B = {2, 5, 14, 16}

Answer 1

A = {2, 6, 10, 14} and B = {2, 5, 14, 16}

A ∪ B = {2, 6, 10, 14} ∪ {2, 5, 14, 16}

= {2, 5, 6, 10, 14, 16}

A ∩ B = {2, 6, 10, 14} ∩ {2, 5, 14, 16}

= {2, 14}

A – B = {2, 6, 10, 14} – {2, 5, 14, 16}

= {6, 10}

B – A = {2, 5, 14, 16} – {2, 6, 10, 14}

= {5, 16}
