Assume the toys are different (distinguishable).


There are  12*11*10*9  different ways to arrange (to place in some order) 4 toys of 12.


There are  12*11*10*9*8  different ways to arrange (to place in some order) 5 toys of 12.


The total number that the problem asks for is the sum 


    12*11*10*9 + 12*11*10*9*8.

It will be your answer, when you compute the value.
