Question 2:

If U = {a, b, c, d, e, f, g, h}, find the complements of the following sets:

(i) A = {a, b, c}

(ii) B = {d, e, f, g}

(iii) C = {a, c, e, g}

(iv) D = {f, g, h, a}

Answer

U = {a, b, c, d, e, f, g, h}

(i) A = {a, b, c}

A΄ = {d ,e f, g, h}

(ii) B = {d, e, f, g}

∴ B΄ = {a, b, c, h}

(iii) C = {a, c, e, g}

∴ C΄ = {b, d, f, h}

(iv) D = {f, g, h, a}

∴ D΄={b, c, d, e}
