Question

Considerando os conjuntos U = {0, 1, 2, 3, 4, 5, 6}, A = {1, 2}, B = {2, 3, 4}, C = {4, 5} determine (U – A) ∩ (B U C).

Answer 1

(U - A) = {0, 1, 2, 3, 4, 5, 6} - {1, 2} = {0, 3, 4, 5, 6}

(B U C) = {2, 3, 4} U {4, 5} = {4}


(U – A) ∩ (B U C) = {0, 3, 4, 5, 6} ∩ {4} = {0, 3, 5, 6}

Portanto, (U – A) ∩ (B U C) = {0, 3, 5, 6}.
