You need to be more clear on what you're having trouble with. There are various sections of probability and statistics that use different formulas. The first probability part, then the various single mean distributions, comparisons between two means, and the list continues you on. Which part are you having issues with?

i believe there only are 3 axioms... but I remembered only one. universe is one, what you want is a fraction of the universe, and that fraction is probability and the remainding universe minus what you what is complement probability.
