You flip a coin ten times you might get 9 heads and 1 tail, which is an unlikely outcome, but flip it a million times and you'll likely get very close to half.

So, there is enough data out there to tell you the probability of getting killed while riding a bike. There are things that you can do to lower or raise your own probability of dying.
