Let `A = { a, e, i, o, u} and B = { a, b, c, d}`. Is A a subset of B ? No. (Why?). Is B a subset of A? No. (Why?)

Let V = { a, e, i, o, u } and B = { a, i, k, u} . Find V – B and B – V

Let A = { a, b }, B = {a, b, c} . Is A ⊂ B ? What is A ∪ B ?

If V={a,e,I,o,u} and B={a,I,k,u}. Find V-B and B-V.

Let A={a,e,I,o,u} and B={a,I,u}. Show that A cup B=A

Let A and B be two non- empty subsets of a set X such that A is not a subset of B .Then

If A and B are finite sets and A subset B , then

Let A = {1, 2}, B = {3, 4} . Write A xx B . How many subsets will A xx B have ?

Let A = ( a, b, c) and R = {(a, a), (b, b), (a, b), (b, a), (b, c)} be a relation on A, then R is

f and h are function from A rarr B, where A = {a, b, c, d} and B = {s, t, u} defined as follows f(a) = t, f (b) = s, f(c ) = s f(d) = u, h(a) = s, h(b) = t h(c ) = s, h(a) = u, h(d) = u Which one of the following statement is true?

Let U = {1, 2, 3, 4, 5, 6}, A = {2, 3} and B = {3, 4, 5} . Find A′, B′ , A′ ∩ B′, A ∪ B and hence show that ( A ∪ B )′ = A′ ∩ B′ .
