Ok thanks. So how would i convert that into the average number of "guesses" needed? is it 1 / (1/2)^4 ?

Yes uniformly random. So the size of of the "byte" doesn't need to be taken into account? For example if I have a SHA 256 hash (256 bits) the probability of generating a hash with 4 leading zeros is the same as generating a byte with 4 leading zeros?
