Question

9. Let A = (1, 2, 3, 4), B = (1, 2, 3] and C = (2, 4). Find all sets X satisfying each pair of
following conditions :
(i) X is the subset of B and X is not the subset of C .
(ii) X is the subset of B,X is not equal to B and X is not the subset of C .
(iii) X is the subset of A,X is the subset of B and X is the subset of C.​

Answer 1

Answer:

X={1,3}

Step-by-step explanation:

For set { } this should be used not()

Answer 2

A = (1,2,3,4)

A = {2,3}

B = (1,2,3]

B = {2,3}

C = (2,4)

C = {3}

i)

X is the subset of B but not subset of C

==> X = {2,3}

and

==> X = {2}

ii)

X is the subset of B, X is not equal to B and X is not subset of C

==> X = {2}

iii)

X is the subset of A, X is the subset of B and X is the subset of C

==> X = {3}
