Question

sejam os conjuntos A = { a, b, c, d }, B = { c, d, e, f, g } e C = { b, d, g}. determine:

a) A-B =
b) B-A =
c) C-B =
d) (A ∪ C) - B =
e) A - ( B ∩ C) =
f) (A ∪ B) - ( A ∩ C ) =

Answer 1

a) {a,b}
b) {e,f,g}
c) {b}
d) {a,b,c,d,g} - {c,d,e,f,g}
= {a,b}
e) {a,b,c,d} - {d,g}
= {a,b,c}
f) {a,b,c,d,e,f,g} - {d,g}
= {a,b,c,e,f}
