Question

Dados os conjuntos A = {a, b, c, d, e, f, g}, B = {b, d, g, h, i} e C = {e, f, m n}, determine:
a) A − B =
b) B – C =
c) B – A =
d) (A – B) ∪ (B – A) =

Answer 1

A) A - B = {a, c, e, f}

B) B - C = {b, d, g, h, i}

B) B - A = {h, i}

d) (A – B) ∪ (B – A) = {a, c, e, f} ∪ {h, i} = {a, c, e, f, h, i}
