Show answer and explanation
Correct Answer
C. 7
ExplanationStep 1: Total subsets are 2^n. Step 2: For n = 3 total subsets are 8 and proper subsets are 8 - 1 = 7. Step 3: A proper subset does not include the whole set.
Step 1: Total subsets 2^n होते हैं। Step 2: n = 3 के लिए total subsets 8 हैं और proper subsets 8 - 1 = 7 होंगे। Step 3: Proper subset में पूरा set शामिल नहीं होता।
