Answer 2

Given:

'r' identical containers filled with 'n' identical balls.

To Find:

What is probability that all containers have at most 2 balls?

Solution:

Since, we know that-

Formula for calculating probability of 'n' identical balls filled in 'r' identical container is;

$\[P(n,r) = \sum\limits_{k = 1}^r {P(n - r,k)} \]$

Here, probability that all containers have at most 2 balls is equal to -

$\[P(n,r) = \sum\limits_{k = 2}^r {P(n - r,2)} \]$
