Answer 2

No. of ways of two identical balls can be placed in 3 different boxes so that exactly one box is empty is 3 ways

Step-by-step explanation:

Total No. of boxes = 3

No. of balls = 2

We are supposed to put the balls in boxes such that exactly one box is empty

So, we will use combination over here

Formula : $^nC_{r=\frac{n!}{r!(n-r)!}$

So, n = 3 and r = 2

$^nC_r=\frac{n!}{r!(n-r)!}$

$^3C_2=\frac{3!}{2!(3-2)!}$

$^3C_2=3$

So,No. of ways of two identical balls can be placed in 3 different boxes so that exactly one box is empty is 3 ways
