| Question 1 |
How many are there to place 8 indistinguishable balls into four distinguishable bins?
| 70 | |
| 165 | |
| 8 C 4 | |
| 8 P 4T |
Question 1 Explanation:
This is precisely the problem we saw to solve the r-combination with repetition:
= C(8+4-1,8)
= 11 C 8
= 11! / (8!(11-8)!)
= 165
= C(8+4-1,8)
= 11 C 8
= 11! / (8!(11-8)!)
= 165
Correct Answer: B
