Explicație pas cu pas:

A = {1, 2, 3, 4, 8, 11, 13, 15}

B = {1, 2, 4, 5, 6, 9, 11, 12}

C = {1, 2, 6, 7, 8, 9, 10, 14, 15 }

A ∪ B = {1, 2, 3, 4, 5, 6, 8, 9, 11, 12, 13, 15}

A ∩ B = {1, 2, 4, 11}

A \ B = {3, 8, 13, 15}

B \ A = {5, 6, 9, 12}

A ∪ B ∪ C = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15}

A ∩ B ∩ C = {1, 2}
