Question

3. If A = {a, b, c) and B = {1, 2, 3, 4, 5), find :
(a) number of proper subsets of A
(b) number of subsets of B
(c) all proper subsets of A​

Answer 1

Answer:

a) Proper subset = 2n - 1

= 2(3) - 1

= 5

b) Subset = 2^n

= 2^5

= 32

c) Proper subsets of A are

= { }, {a}, {b}, {c}, {a, b}, {a, c}, and {b, c}.

HOPE THIS HELPS YOU......

Answer 2

Answer:

( a ) A(n) = 3

number of proper subsets of A

= 2n-1

= 2×3-1

=5

( b ) number of subset of B (n ) = 5

( c ) all proper subset of A

= { { }, { a }, { b }, { c }
