Question

15. Sea Re = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11}, y, A, B y C conjuntos no vacíos tales que CC ∩ B = {2, 4, 7}; A U B = {2, 5, 8}; C – (A U B) = {1, 3}; A = {2, 5, 8, 10, 11}; A ∩ C = {5, 8, 10}, Re – (A U B U C) = {6}. Entonces AC – B es
a) {1, 3, 4, 6}
b) {4, 6}
c) {8, 7, 8, 9}
d) {1, 6, 7}
e) {1, 3, 6}

Answer 1

Respuesta:

e)

Explicación:

A' — B

= {1; 3; 4; 6; 7; 9} — {2; 4; 5; 7; 8; 9}

= {1; 3; 6}
