\(\binom{9}{4}+\binom{9}{5}\) पास्कल पहचान से किसके बराबर है?
Using Pascal's identity \(\binom{9}{4}+\binom{9}{5}\) is equal to which expression?
Explanation opens after your attempt
Correct Answer
A. \(\binom{10}{5}\)
Step 1
Concept
By Pascal's identity \(\binom{n}{r}+\binom{n}{r+1}=\binom{n+1}{r+1}\). Hence the answer is \(\binom{10}{5}\).
Step 2
Why this answer is correct
The correct answer is A. \(\binom{10}{5}\). By Pascal's identity \(\binom{n}{r}+\binom{n}{r+1}=\binom{n+1}{r+1}\). Hence the answer is \(\binom{10}{5}\).
Step 3
Exam Tip
पास्कल पहचान से \(\binom{n}{r}+\binom{n}{r+1}=\binom{n+1}{r+1}\) होता है। इसलिए उत्तर \(\binom{10}{5}\) है।
