Question

Fill in the blanks with elements of that set.

U = {1, 3, 5, 8, 9, 10, 11, 12, 13, 15}

A = {1, 11, 13} B = {8, 5, 10, 11, 15}

A' = {........} B' = {........}

A ∩ B = {............}

A' ∩ B' = {...............}

A ∪ B = {............}

A' ∪ B' = {............}

(A ∩ B)' = {............}

(A ∪ B)' = {............}

Answer 1

A' = {3, 5, 8, 9, 10, 12, 15} B' = {1, 3, 9, 12, 13}

A ∩ B = {11}

A' ∩ B' = {3, 9, 12}

A ∪ B = {1, 5, 8, 10, 11, 13, 15}

A' ∪ B' = {1, 3, 5, 8, 9, 10, 12, 13, 15}

(A ∩ B)' = {1, 3, 5, 8, 9, 10, 12, 13, 15}

(A ∪ B)' = {3, 9, 12}
