(L) There are 3 different numbers (1,2,3) L=3
(O) There are 4 numbers in total (1,1,2,3) O=4
(LO) 3x4=12. LxO=12
There are 12 possible combinations.

If there were 4 different digits(One of each number)e.g.1,2,3,4, then there would be 16 different combinations. Because there are two different ones, swapping them would create the same number.
