Correct Answer

C. (350)

Step 1

Concept

The possible cases are (2G3B) and (3G2B). The sum is \(^{5}C_{2}\times{}^{6}C_{3}+^{5}C_{3}\times{}^{6}C_{2}=350\).

Step 2

Why this answer is correct

The correct answer is C. (350). The possible cases are (2G3B) and (3G2B). The sum is \(^{5}C_{2}\times{}^{6}C_{3}+^{5}C_{3}\times{}^{6}C_{2}=350\).

Step 3

Exam Tip

संभव मामले (2G3B) और (3G2B) हैं। योग \(^{5}C_{2}\times{}^{6}C_{3}+^{5}C_{3}\times{}^{6}C_{2}=350\)।
