Greetings Mathlings,(adsbygoogle = window.adsbygoogle || []).push({});

I am Tegga from a different planet, where the knowledge of maths is very ordinary. I need your help. I am looking for a formula to rank 2 sets of numbers. The first set is, say 1 to 12 - but it could be anything from 1 to a maximum of 30. The second set is again, say 10, but could be anything from 1 to 30.

If I combine the 2 lists in every possible combination, eg 1-1, 1-2....12-10. There would be a total possible 120 combinations in a list of 10 and 12. The combination of 1-1 is the most likely combination, while the combination of 12-10 is the least likely.

What I am looking for is a formula which will give a weighting of the probability of any particular combination, so that the whole 120 combinations have some sort of probability rating. The problem is that as we move down the list, the likelihood of each combination gets less, but not in a linear fashion.

Is there such a formula, do you know?

Thanks

tegga
