Answer 1

Resposta:

Resposta da letra A está em anexo.

Respostas da letra B:

A ∪ B ∪ C = {0, 2, 4, 6, 8, 10, 15, 16, 20, 22, 28, 30}

A ∩ B ∩ C = {4, 10, 20}

A - ( B ∪ C ) = {0, 6, 15}

( A ∪ B ) ∩ ( B ∪ C ) = {2, 4, 8, 10, 20, 30}

Explicação passo a passo:

A = {0, 2, 4, 6, 10, 15, 20}

B = {2, 4, 8, 10, 20, 30}

C = {4, 10, 16, 20, 22, 28}

b)

A ∪ B ∪ C = {0, 2, 4, 6, 8, 10, 15, 16, 20, 22, 28, 30}

A ∩ B ∩ C = {4, 10, 20}

A - ( B ∪ C ) ∴ A - {2, 4, 8, 10, 16, 20, 22, 28, 30} = {0, 6, 15}

( A ∪ B ) ∩ ( B ∪ C ) ∴ {0, 2, 4, 6, 8, 10, 15, 20, 30} ∩ {2, 4, 8, 10, 16, 20, 22, 28, 30} = {2, 4, 8, 10, 20, 30}
