My ceiling fan has black, white, and a black/white wire?
	
	
		Can someone please help me with this combination of wires?  I am trying to change out ceiling fans in my living room. 
From ceiling box I have:  a black wire, and a white wire, and no ground 
From the fan w/ light kit I have:  a black wire, white wire, and a black w/ while stripe wire, and no ground
Do I attach the three black wires and the two whites?  Don't I need to have some type of ground wire? 
It is a Hunter ceiling fan if that helps. 
Thanks!
