I used to love calculating probabilities at school :) (which probably says a lot about me).

It's quite easy if you looks at it. "n" the number of years, is always above the line, i.e. it multiplies things, because, if you think about it, the longer you wait the more likely it is that something will happen. "k" is always below the line, i.e it divides things, because it is some sort of parameter for the severity of the event you are trying to predict. It makes sense that the more severe an event, the less likely it is. "P" and "q" are given parameters so you don't have to worry abuot them. Factorialising the numbers (the "!" symbol; multiplying 4*3*2*1, for example, for 4!) just gives you the number of permutations you are working with in the core part of your equation. Sorry if I'm teaching my grandmother to suck eggs :D

Not at all. Thank you very much. Hearing it from a "different angle", so to speak, is good.

"Serious and negligible flooding probabilities of an area of land within the Vale of Glamorgan with a proposed development plan ." Exciting stuff.
