Question

sendo U= (1,2,3,4,5,6,7,8,9) A= (1,3,5,7,9) B= (2,4,6,8) e C= (1,2,3,5) Calcule: a) AUC. b) BUC c) A⋂B d)A⋂C e)A-C f) C-A g) A-B h) B-A​

Answer 1

Resposta:

U= (1,2,3,4,5,6,7,8,9)   ....A= (1,3,5,7,9) ...B= (2,4,6,8)    e   C= (1,2,3,5)

a) AUC  = {1,2,5,7,9,3}

b) BUC  = {2,4,6,8,1,3,5}

c) A⋂B  = (1,3,5)

d)A⋂C =(1,3,5)

e)A-C  =(7,9)

f) C-A =(2)

g) A-B  = (1,3,5,7,9)

h) B-A​=(2,4,6,8)
