Explanation opens after your attempt
Correct Answer

A. \(\frac{8!}{3!3!2!}\)

Step 1

Concept

For labelled groups, group names are fixed so only internal order is removed. In exams use factorial denominators for fixed group sizes.

Step 2

Why this answer is correct

The correct answer is A. \(\frac{8!}{3!3!2!}\). For labelled groups, group names are fixed so only internal order is removed. In exams use factorial denominators for fixed group sizes.

Step 3

Exam Tip

Labelled groups में group names fixed होते हैं इसलिए सिर्फ internal order हटता है। परीक्षा में fixed group sizes के factorial denominator लगाएं।
