martyn willis asked the Naked Scientists:
   Is there a law of improbability and if so what is it?
What do you think?

[Fruityloop]

I think there may be, such as: If the probability of an event occurring is sufficiently small, the probability is equal to zero.  If the probability is less than 10^-50, one could make a valid argument that it will never occur.  Although the cutoff point is obviously subject to dispute.

[Colin2B]

If the probability of an event is p, then you could say that it's improbability is 1-p.
In that case the law of improbability is implicit in the law of probability.

[jeffreyH]

Say there is a 3 in 4 chance of an event occurring. Then p = 3/4. So that 1 - p is 1/4. That seems to be a reasonable definition of improbability.

[jeffreyH]

If we can compute an improbability density and combine it with infinite Feynman diagrams we may yet be able to build the infinite improbability drive.

You will then have a heart of gold Mr Jeffrey...... and probably a brain the size of a planet.
But don't let that depress you []
