1. Statistically, the chance of being on a plane with TWO bombs is much less than being on a plane with ONE bomb. OK, both are pretty small probabilities, but surely it would be safer to take your own bomb on board a plane just to reduce the chance of another bomb being on board!!!

2. It is safer to drive at 100mph in a 30mph zone - statistically, hardly anyone crashes at 100mph, but loads at 30mph!

Have you any more?

if the universe were to go on for an infinite distance / time, would it mean there is a 100% chance to anything happening for example an identical planet earth, or even something we drum up in our heads like an actual version of the star was fleet.
