\(\binom{12}{5}+\binom{12}{6}\) पास्कल पहचान से किसके बराबर है?
Using Pascal's identity \(\binom{12}{5}+\binom{12}{6}\) is equal to which expression?
Explanation opens after your attempt
Correct Answer
A. \(\binom{13}{6}\)
Concept
By Pascal's identity \(\binom{n}{r}+\binom{n}{r+1}=\binom{n+1}{r+1}\). Hence the answer is \(\binom{13}{6}\).
Why this answer is correct
The correct answer is A. \(\binom{13}{6}\). By Pascal's identity \(\binom{n}{r}+\binom{n}{r+1}=\binom{n+1}{r+1}\). Hence the answer is \(\binom{13}{6}\).
Exam Tip
पास्कल पहचान से \(\binom{n}{r}+\binom{n}{r+1}=\binom{n+1}{r+1}\) होता है। इसलिए उत्तर \(\binom{13}{6}\) है।
