(12) अलग वस्तुओं को (4,4,4) के unlabelled समूहों में बांटने का formula क्या होगा?
What is the formula for dividing (12) distinct objects into unlabelled groups of (4,4,4)?
Explanation opens after your attempt
Correct Answer
B. \(\frac{12!}{4!4!4!3!}\)
Concept
All three groups have equal size and are unlabelled, so the (3!) interchange of groups is also removed. In exams divide extra by factorial for equal unlabelled groups.
Why this answer is correct
The correct answer is B. \(\frac{12!}{4!4!4!3!}\). All three groups have equal size and are unlabelled, so the (3!) interchange of groups is also removed. In exams divide extra by factorial for equal unlabelled groups.
Exam Tip
तीनों groups equal size और unlabelled हैं, इसलिए groups की (3!) अदला-बदली भी हटती है। परीक्षा में समान unlabelled groups पर extra factorial divide करें।
