From the given Venn diagram, write the elements of
(i) A
(ii) B
(iii) A – B
(iv) B – A
(v) A′
(vi) B′
(vii) U
2.
If A = {6, 7, 8, 9} and B = {8, 10, 12}, find A Δ B.
3.
If A = {–3, –2, 1, 4} and B = {0, 1, 2, 4}, find
(i) A – B
(ii) B – A.
4.
If A = {1, 2, 6} and B = {2, 3, 4} , find A∪B.
5.
Find the number of subsets and the number of proper subsets of a set X = {a, b, c, x, y, z}.
6.
Insert the appropriate symbol \(\subseteq \) or \(\nsubseteq \) in each blank to make a true statement.
{p, q, r} _____ {w, x, y, z}
7.
Insert the appropriate symbol \(\subseteq \) or \(\nsubseteq \) in each blank to make a true statement.
{10, 20, 30} ____ {10, 20, 30, 40}
8.
Write all the subsets of A = {a, b}.

ASSESSMENT
1.
(i) A = {a, e, i, o, u}
(ii) B = {b, c, e, o}
(iii) A – B = {a, i, u}
(iv) B – A = {b, c}
(v) A′ = {b, c, d, g}
(vi) B′ = {a, d, g, i, u}
(vii) U = {a, b, c, d, e, g, i, o, u}.
2.
A – B = {6, 7, 9}
B – A = {10, 12}
A Δ B = (A – B) ∪ (B – A) = {6, 7, 9} ∪ {10,12}
A Δ B = {6, 7, 9, 10, 12}.
3.
A – B = {–3, -2, 1, 4} – {0, 1, 2, 4} = { -3, -2}
B – A = {0, 1, 2, 4} – {–3, -2, 1, 4} = { 0, 2}.
4.
Given A = {1, 2, 6}, B = {2, 3, 4}
A∪B = {1,2,3, 4,6}.
5.
Given X = {a, b, c, x, y, z}.Then, n(X) = 6
The number of subsets = n[P(X)] = 26 = 64
The number of proper subsets = n[P(X)]-1 = 26 – 1
= 64 – 1 = 63.
6.
{p, q, r} _____ {w, x, y, z}
Since the element p belongs to {p, q, r} but does not belong to {w, x, y, z}, shows that {p, q, r} \(\nsubseteq \) {w, x, y, z}.
7.
{10, 20, 30} ____ {10, 20, 30, 40}
Since every element of {10, 20, 30} is also an element of {10, 20, 30, 40}, we get {10, 20, 30} \(\subseteq \) {10, 20, 30, 40}.
8.
A= {a,b}
Subsets of A are \(\phi \),{a}, {b} and {a, b}.
9.
PRINCIPAL
B = {P, R, I, N, C, A, L}

A= {A, S, E, M, N, T}
