According to the question, 25% of all serious bicycle accidents involve head injuries.
That means, out of every 100 serious bicycle accidents, 25 involve head injuries.
80% of those 25 are fatal.
80% of 25 = x 25 = 20.
So out of 100 serious bicycle accidents, 20 of them involve fatal head injuries.
So the answer is 20%
