Question

considere o diagrama a seguir e determine:
A) AUB
B) B^C
C) (AUB) ^C
D) (B^C) UA
E) A^B^C
F) (AUB) ^ (AUC)​

Answer 1

Resposta:

Considerando que:

A = {1,2,3,4,8}

B = {3,4,5,7}

C = {4,6,7,8}

Temos:

A U B = {1,2,3,4,5,7,8}

A n B = {4,7}

(A U B) n C = {7,4,8}

(B n C) U A = {1,2,3,4,7,8}

A n B n C = {4}

(A U B) n (A U C) = {1,2,3, 4,7,8}
