Answer 1

Ответ:

Пошаговое объяснение:

A={1,3,5,7,9,11}, B={2,5,6,11,12}, C={1,2,3,5,9,12}

а) (A\C)ΔB=({1,3,5,7,9,11}\{1,2,3,5,9,12})Δ{2,5,6,11,12}={7,11}Δ{2,5,6,11,12}={7}Δ{2,5,6,12}={2,5,6,7,12}

б) (A∩C)∪B=({1,3,5,7,9,11}∩{1,2,3,5,9,12})∪{2,5,6,11,12}={1,3,5,9}∪{2,5,6,11,12}={1,2,3,5,6,9,11,12}

в) C\B\A={1,2,3,5,9,12}\{2,5,6,11,12}\{1,3,5,7,9,11}={1,3,9}\{1,3,5,7,9,11}=∅
