Question

Dados los conjuntos

U = {1; 2; 3; 4; 5; 6; 7; 8; 9; 10; 11; 12; 13}

A = {3; 5; 6; 7; 9; 11}

B = {1; 4; 5; 8; 12}

C = {1; 2; 3; 5; 7; 11; 13}

Determine (C' – A) ∩ B'

A){10}

B){9}

C){7}

D){11}

E){12}





Y DE PASO PORFAA



U = {x/x ∈ +; x < 12}

A = {2x/x ∈ +; x < 5}

B = {3x/x ∈ +; x < 4}

C = {1; 5; 6; 9; 10; 11}

Determine (A' ∩ B') -C


A) {10}

B) {9}

C) {7}

D) {11}

E) {12}


OTRO MAS :)))

Si n(A) = 72
n(B) = 56
n(C) = 73
n(A∩ B) = 19
n(A∩ C) = 21
n(B∩ C) = 22
n(A∩ B∩ C) = 9
Calcule n(A∪ B∪ C).
A) 152
B) 127
C) 148
D) 144
E) 160

Answer 1

Respuesta:

A C C

Explicación paso a paso:

1){{4, 6, 9, 10, 12} - A} ■ {2, 3, 6, 7, 9,10, 11, 13}

{4, 10, 12} ■ {2, 3; 6 , 7, 9, 10, 11, 13}

{10}

2)U= {1,2,3,4,5,6,7;8,9,10,11}

A={2,4,6,8}

B={3,6,9}

C={1,5,6,9,10,11}

{{1,3,5,7,9,10,11}■{1,2,4,5,7,8,10,11}}-C

{1,5,7,10,11}}-{1,5,6,9,10,11}

{7}

3)n(A U B U C}
