Based on the fact that the identical darts were thrown at four identical dartboards and Ben took a list, the number of different lists possible is 5 lists.
If all the darts hit on dartboard then the list would be:
= 0004
If one dart hit a dartboard and three hit one dartboard the list would be:
= 0031
If two darts hit two boards:
= 0022
If two darts hit one board, 1 dart two others:
= 0211
If all darts hit separate boards;
= 1111
This means that 5 lists are possible to Ben.
