Question

dados os conjuntos o conjunto é

Answer 1

A = {a, b, c}

B = {b, c, d}

C = {a, c, d, e}

 

(A-C) = {a, b, c} - {a, c, d, e} = {b}

(C-B) = {a, c, d, e} - {b, c, d} = {a, e}

(A∩B∩C) = {a, b, c} ∩ {b, c, d}∩ {a, c, d, e} = ({a, b, c} ∩ {b, c, d})∩ {a, c, d, e} =

{b, c }∩ {a, c, d, e} = {c}

 

 

(A-C) U (C-B) U (A∩B∩C) = {b} U {a, e} U {c} = {a, b, c, e}
