I came upon this questions on one of my tests, and wasn't able to solve it. Was wondering if anyone could point me in the right direction. Thanks in advance.
Let m be the number of ways 3 identical balls can be put into 3 identical boxes.
Let n be the number of ways 3 different balls can be put into 3 identical boxes.
Let p be the number of ways 3 different balls can be put into 3 different boxes.
And let k denote the number of ways 3 identical balls can be put into 3 different boxes.
What is the value of m+n+p+k?
Is there a formula for this or is it concept based?
