Question

Se dau multimile: A = {1, 3, 4, 8, 9, 10} si B = {1, 2, 3, 4, 6, 7, 8, 10}
Calculati: A reunit cu B; A intersectat cu B; A-B; B-A

Answer 1

A reunit cu B = 1,2,3,4,6,7,8,9,10

A intersectat cu B= 1,3,4,8,10

A-B=9

B-A=2,6,7

Answer 2

    A = {1, 3, 4, 8, 9, 10}

    B = {1, 2, 3, 4, 6, 7, 8, 10}

    A ∪ B = {1, 2, 3, 4, 6, 7, 8, 9, 10}

    A ∩ B = {1, 3, 4, 8, 10}

    A - B = {9}

    B - A = {2, 6, 7}
