This is again a table question...
Let's write out what we're told specificially:
B W total
H 8
-H 5
------------
4
We can use this to fill out the rest of the table (I've starred* these):
B W total
H 1* 7* 8
-H 3* 5 8*
------------
t 4 12* 16
The BH combination is what we're looking for: the answer is 1.
