Explanation opens after your attempt
Correct Answer

D. (37)

Step 1

Concept

Count subsets of sizes (6), (7), and (8). The sum is \(^{8}C_{6}+^{8}C_{7}+^{8}C_{8}=37\).

Step 2

Why this answer is correct

The correct answer is D. (37). Count subsets of sizes (6), (7), and (8). The sum is \(^{8}C_{6}+^{8}C_{7}+^{8}C_{8}=37\).

Step 3

Exam Tip

आकार (6), (7), और (8) के उपसमुच्चय गिनें। योग \(^{8}C_{6}+^{8}C_{7}+^{8}C_{8}=37\)।
