Question

dados A={ 0,1,2,3,4}, B={ 1,2,3} e C={2,3,4,5}, determine:a) (A-B) U ( B-C)= b) (A-C) n (B-A)= c) (AnB)-C d) (BuC)-A= Mim ajudeeeeem :(

Answer 1

a) (A-B) U (B-C)=
{0,4} U {1}= {0,1,4}

b) (A-C) ∩ (B-A)=
{0,1} ∩ {∅} = {∅}

c) (A∩B) - C=
{1,2,3} - {2,3,4,5} =
{1}

d) (B∪C)-A=
{1,2,3,4,5} - {0,1,2,3,4}= {5}
