2. Misalkan himpunan semesta S = {a, b, c, d, e, f, g} A = {a, b, c, d, e} B = {a, c, e, g} dan C = {b, e, f, g}. Tentukan:
a. (AnC) UB
b. A-BC​

Jawab:
a.
(AnC) UB = {a, b, c, e, g}
b. A-B' = {a, c, e}

Penjelasan:
S = {a, b, c, d, e, f, g}
A = {a, b, c, d, e}
B = {a, c, e, g} dan
C = {b, e, f, g}

a. (AnC) UB
A = {a, b, c, d, e}
C = {b, e, f, g}
AnC = {b, e}
UB
B = {a, c, e, g}
(AnC) UB = {a, b, c, e, g}

b. A-B'
{a, b, c, d, e}  - {b, d, f} =
A-B' = {a, c, e}
