Something done haphazardly seems completely random, like your little sister's collage of pictures cut carelessly from a magazine and haphazardly glued all over a piece of poster board.
The adverb haphazardly is good for describing something done in an unplanned or random way without concern for the outcome; for example, you might put silverware away by haphazardly tossing it in a drawer, or plant a crazy garden with flowers haphazardly placed here and there around the yard. Haphazardly combines hap, meaning "chance," with hazard, or "danger."
