Brain Game: No Mulligans

Four friends - Jerry, Will, Roy, and Dan - head to a local course to enjoy 18 holes of golf. Given that all four men finish the round, and that ties can occur between players:

75.

24 different orders are possible if each player has a different score, and another 51 possible finishes involve tie scores between players.
