Number of Subsets of a given Set:

1 = If a set contains 'n' elements, then the number of subsets of the set is 22.

2 = If a set contains 'n' elements, then the number of proper subsets of the set is 2n - 1.

⇒ Number of proper subsets of A are 3 = 22 - 1 = 4 - 1.

Answer 2

Answer:

$subsets = 2 {}^{n}$

$n \: is \: no \: of \: elements = 2$

$subsets = 2 {}^{2}$

$subsets = 4$
