B={3 , 9, 8, 10, 11]
Grafique e indique si las siguientes proposiciones son verdaderas(V) o falsas(F)
8 ϵ (A∩B) _______________
9 ϵ (A∩B) _______________
(A∪B) -- (A∩B) = {1, 5, 7, 8, 10, 11} __________________

con gráfica ​

Answer 1

Explicación paso a paso:

A= {1, 3, 5, 7, 9, 12}

B= {3, 8, 9, 10, 11}

(F) 8 ∈ (A∩B)

A∩B = {3, 9}, Entonces 8 ∉ A∩B

(V) 9 ∈ (A∩B)

(F) (A∪B) — (A∩B) = {1, 5, 7, 8, 10, 11}

A∪B = {1, 3, 5, 7, 8, 9, 10, 11, 12}

A∩B = {3, 9}

Entonces:

(A∪B) — (A∩B) = {1, 5, 7, 8, 10, 11, 12}
