Răspuns:

a)

A = {1, 4, 5}

B = {2, 4, 5, 6}

C = {3, 5, 6}

==================

b)

F = {1}

G = B ∩ C = {2, 4, 5, 6} ∩ {3, 5, 6} = {5, 6}

H = B ∪ C = {2, 4, 5, 6} ∪ {3, 5, 6} = {2, 3, 4, 5, 6}

I = A ∪ B ∪ C = {1, 4, 5} ∪ {2, 4, 5, 6} ∪ {3, 5, 6} = {1, 2, 3, 4, 5, 6}

J = A ∩ C = {1, 4, 5} ∩ {3, 5, 6} = {5}

K = B \ C = {2, 4, 5, 6} \ {3, 5, 6} = {2, 4}
