\(\binom{8}{3}+\binom{8}{4}\) पास्कल पहचान से किसके बराबर है?
Using Pascal's identity \(\binom{8}{3}+\binom{8}{4}\) is equal to which expression?
Explanation opens after your attempt
Correct Answer
A. \(\binom{9}{4}\)
Concept
By Pascal's identity \(\binom{n}{r}+\binom{n}{r+1}=\binom{n+1}{r+1}\). Hence the answer is \(\binom{9}{4}\).
Why this answer is correct
The correct answer is A. \(\binom{9}{4}\). By Pascal's identity \(\binom{n}{r}+\binom{n}{r+1}=\binom{n+1}{r+1}\). Hence the answer is \(\binom{9}{4}\).
Exam Tip
पास्कल पहचान से \(\binom{n}{r}+\binom{n}{r+1}=\binom{n+1}{r+1}\) होता है। इसलिए उत्तर \(\binom{9}{4}\) है।
