Question

Dane są zbiory A= {1,2,3,4,5,6,7} B={3,4,5,7,8} C={4,5,6,7,8,9}.
Wyznacz (AuBuC), (AuB), (AuC), (AuB)/C (AuC)/B

Answer 1

AuBuC={1,2,3,4,5,6,7,8,9}
AuB={1,2,3,4,5,6,7,8}
AuC={1,2,3,4,5,6,7,8,9}

(AuB)/C={1,2,3}

(AuC)/B={1,2,6,9}

Answer 2

(AuBuC) = {1,2,3,4,5,6,7,8,9}
(AuB) = {1,2,3,4,5,6,7,8}
(AuC) = {1,2,3,4,5,6,7,8,9}
(AuB)/C = {1,2,3}
(AuC)/B = {1,2,6,9}
Gotowe. :)
Jak dasz naj, będzie miło ;)
