balls are distributed among boxes, then the probability that the first box will contain balls is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
Here, since each ball can be placed in any one of the 3 boxes, therefore there are 3 ways in which a ball can be placed in any one of three boxes. Thus, there are 312 ways in which 12 balls can be placed in 3 boxes. The number of ways in which 3 balls out of 12 can be put in the…
