यदि \(A=\{a,b,c,d\}\), तो (\mathcal{P}(A)) में ठीक (2) तत्वों वाले कितने उपसमुच्चय होंगे?

If \(A=\{a,b,c,d\}\), how many subsets with exactly (2) elements are in (\mathcal{P}(A))?

Explanation opens after your attempt
Correct Answer

A. (6)

Step 1

Concept

The number of ways to choose exactly (2) elements is \(\binom{4}{2}=6\). The power set contains subsets of every size.

Step 2

Why this answer is correct

The correct answer is A. (6). The number of ways to choose exactly (2) elements is \(\binom{4}{2}=6\). The power set contains subsets of every size.

Step 3

Exam Tip

ठीक (2) तत्व चुनने के तरीके \(\binom{4}{2}=6\) हैं। घात समुच्चय में सभी आकारों के उपसमुच्चय होते हैं।
