Assistance with statistical analysis

In South Africa there are 10 million registered self propelled vehicles.

Of these vehicles, 300,000 are mini bus taxis.



The death toll on South African roads average 35 deaths/day.



3 of these deaths are attributed to mini bus accidents.



3% of the total number of vehicles are responsible for 8.5% of the deaths.



How factual is the claim that mini bus taxis are 3 to 10 times safer than other vehicles?
