How many ways are there to distribute three different teddy bears and nine identical lollipops to four children with each child getting three "goodies"?
I am stuck on how to approach this problem. I know that the number of "goodies" is equal to $12$.
We can distribute $3$ teddy bears to $4$ children in $4^3$ ways.
We can ensure that each child gets $3$ goodies by filling out each child with lollipops.
So, there are a total of $4^3=64$ ways
