Question

find proper subsets of setB={x,y}​

Answer 1

Answer:

If A and B are two sets, and every element of set A is also an element of set B, then A is called a subset of B and we write it as A ⊆ B or B ⊇ A

The symbol ⊂ stands for ‘is a subset of’ or ‘is contained in’

• Every set is a subset of itself, i.e., A ⊂ A, B ⊂ B.

• Empty set is a subset of every set.

• Symbol ‘⊆’ is used to denote ‘is a subset of’ or ‘is contained in’.

• A ⊆ B means A is a subset of B or A is contained in B.

• B ⊆ A means B contains A.

Answer 2

Answer:

set B={x,y}

proper subset is a subset which is not equal to the given set ie., proper set of B contain

$<$

in B

therefore propers set of B are 1)nill set {}

2) {x}

3){y}
