Translation Help

[Michael Mortensen]

Could someone help me by translating a couple of entries from a 1885 Census record for a Mortensen household in Copenhagen.
What does "Arbeidsmand,tilfældig" mean?
2. What does "arbeider" mean?
Tak,
Michael Mortensen

[Ralph Rasmussen]

Arbeid is labor. Arbeidsmand, laborer.  If also tilfældig, he is a day laborer. As a noun, arbeider is worker, as a verb 'works'.
