(11) वस्तुओं में से (8) चुनने के बजाय (3) छोड़ने का तरीका कौन-सा formula दिखाता है?
Which formula shows choosing (8) from (11) as leaving (3)?
Explanation opens after your attempt
A. \(^{11}C_8=^{11}C_3\)
Concept
Choosing (8) means leaving (3) so both combinations are equal. In exams replace large (r) with the smaller complement.
Why this answer is correct
The correct answer is A. \(^{11}C_8=^{11}C_3\). Choosing (8) means leaving (3) so both combinations are equal. In exams replace large (r) with the smaller complement.
Exam Tip
(8) चुनना (3) छोड़ना है इसलिए दोनों combinations बराबर हैं। परीक्षा में बड़े (r) को छोटे पूरक से बदलें।
