The number of ways is which 3 identical balls can be distributed into 7 distinct bins is
- A 49
- B 84
- C 35
- D 42
Answer & Solution
Correct Answer
(B) 84
Step-by-step Solution
Detailed explanation
Given, 3 identical balls can be distributed into 7 distinct bins. i.e \(x_1+x_2+x_3+x_4+x_5+x_6+x_7=3\) \(\therefore\) Total number ways : \({ }^{7+3-1} C_{7-1}={ }^9 C_6=84\)
