Działania na zbiorach

Jeżeli A = {1, 3, 5, 7, 9}

i B = {2, 3, 5, 7},

to suma tych zbiorów

• A ∪ B = {1, 3, 5, 7, 9}

• A ∪ B = {1, 2, 3, 7, 9}

• A ∪ B = {1, 2, 3, 5, 9}

• A ∪ B = {1, 2, 3, 5, 7, 9}

Jeśli A = {1, 3, 5, 7, 9} i

B = {2, 3, 5, 7},

to iloczyn zbiorów A i B

• A ∩ B = { 5, 7, 9}

• A ∩ B = {2, 5, 7}

• A ∩ B = {3, 5, 7}

• A ∩ B = {1, 3, 5, 7, 9}

Wyznacz A∩B, jeśli A={0,1,2,3,4,5,6,7,8,}, B={8,10,11,12,13}

• {0,1,2,3,4,5,6,7,8,10,11,12,13}

• {0,1,3,4,5,6,7}

• {8}

• {10,11,12,13}

Wyznacz AUB, jeśli A={1,3,5,7,9}, B={0,3,6,9}

• {3,9}

• {0,1,3,5,6,7,9}

• {0,1,5,6,7}

• {0,6}

Wyznacz A∩B, jeśli A={2,4,6,8,10,12}, B={1,3,5,7,9}

• A∩B={1,2,3,4,5,6,7,8,9,10,12}

• A∩B={2,4,6,8,10,12}

• A∩B={1,3,5,7,9}

• Zbiór pusty

Wyznacz AUB, jeśli A={-2,-1,0,1,3}, B={2,4,5,6}

• {-2,-1,0,1,2,3,4,5,6}

• Zbiór pusty

• {-2,-1,0,1,3,4,5,6}

• {-2,-1,0,1,2,3,5,6}
