Question

The number of subsets of the set A = {p,q} is

• A. 2
• B. 4
• C. 3
• D. 0

Answer 1

The Correct Option is B

Given the set A = {p, q}, we want to find the number of subsets of A.

The number of subsets of a set with n elements is given by 2ⁿ.

Here, A has 2 elements (n = 2), so the number of subsets is 2² = 4.

These subsets are:

1. The empty set: ∅
2. {p}
3. {q}
4. {p, q}

Therefore, the correct answer is (2) 4.
