I need assistance with a statistics project. I need to compare a list of scores in a matrix. There are 10 scores and I need to compare each individual score to all the other scores (9). What would the equation look like?

.29, 13, 09, 1, 15, 21, 005, 2, 07, 11

Each number represents a scenario score. How can I determine which scenario is most likely to occur over the other scenarios? From what I understand there is an equation that can compare each scenario to the other scenario scores.

I don't understand how the probability is determined, is it simply linearly proportional to score?

So you would have individual score/total score = probability of getting that score
