In how many ways can 12 identical apples be distributed among 4 children if each gets at least 1 apple and not more than 4 apples?
Let us know see the possible groups -1. 3+3+2+0No. of ways = 4!/2! = 122. 3+3+1+1No. of ways = 4!/(2!)(2!) = 63. 3+2+2+1No. of ways = 4!/2! = 124. 2+2+2+2No. of ways = 4!/4! = 1So, the total no. of possible ways = 12+6+12+1= 31 Answer.
Let us know see the possible groups -
1. 3+3+2+0
No. of ways = 4!/2! = 12
2. 3+3+1+1
No. of ways = 4!/(2!)(2!) = 6
3. 3+2+2+1
4. 2+2+2+2
No. of ways = 4!/4! = 1
So, the total no. of possible ways = 12+6+12+1
= 31 Answer.
