\(^{15}C_{7}+^{15}C_{8}\) का सरल मान किसके बराबर है?
The simplified value of \(^{15}C_{7}+^{15}C_{8}\) is equal to what?
Explanation opens after your attempt
D. \(2,^{15}C_{7}\)
Concept
Since \(^{15}C_{8}=^{15}C_{7}\), the sum is \(2,^{15}C_{7}\). By Pascal's rule it is also \(^{16}C_{8}\).
Why this answer is correct
The correct answer is D. \(2,^{15}C_{7}\). Since \(^{15}C_{8}=^{15}C_{7}\), the sum is \(2,^{15}C_{7}\). By Pascal's rule it is also \(^{16}C_{8}\).
Exam Tip
क्योंकि \(^{15}C_{8}=^{15}C_{7}\), योग \(2,^{15}C_{7}\) है। पास्कल से यह \(^{16}C_{8}\) भी है।
