Since the number of outcomes with the 4H and 4T is C (8,4)=70, there is an equal possibility for the rest of outcomes to be more heads than tails, or more tails than heads. Knowing that the total outcomes of flipping a coin 8 times are 256. the difference 256-70 will split equally. so: (256-70)/2=93. P (h>t)=93/256.
