It’s funny how certain things will occur no matter how small the odds are. Such as winning the lottery, surviving a plane crash, or even the emergence of life on Earth. All these have been known to happen, but ever so sparsely.
When it comes to determining the probability of things happening or not, maths and physics come in very handy. An event that has a 0.00001% probability of occurring will indeed occur if the right conditions are met, or if enough time passes (according to a very popular theorem involving a monkey and a typewriter).
