How many distinct arrangements can be formed from the letters of (BALLOON)?शब्द (BALLOON) के अक्षरों की कितनी भिन्न व्यवस्थाएं बनेंगी?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (1260)(1260)
There are (7) letters with (L) and (O) each repeated twice, so the count is (7!/(2!2!)). Repeated letters are not treated as distinct objects.(7) अक्षरों में (L) और (O) दो-दो बार हैं, इसलिए संख्या (7!/(2!2!)) है। समान अक्षर हर बार अलग वस्तु नहीं माने जाते।
