Question

Fie multimileA={1,2,3,5}, B={0,2,4,6} şi C={1,3,6,7,8,9}. Calculează B∪A; A∩ B ; (AUB)UC; AU(BUC); B∩A

Answer 1

BUC 0 2 4 6 1 3 7 8 9 AIntersect B 2

Answer 2

A={1,2,3,5}, B={0,2,4,6} şi C={1,3,6,7,8,9}.

B∪A = { 1,2,3,5,0,4,6}

A∩ B = { 2}

(AUB)UC ={1,2,3,5,0,4,6}U{1,3,6,7,8,9}={0,1,2, 3, 4, 5, 6,7,8,9}

AU(BUC)  ; (BUC)={0,2, 1 ,4, 3,  6,7,8,9}

B∩A = {2}
