Probabilities of Toto

I have calculated the probabilities of the different bets in Toto. It has taken me a longer time than expected (oh well, probability is not really my forte). Anyway, the odds and returns seem to make sense. Please give me some feedback if you think otherwise. Oh, I don't really know how Sys Roll works. Only the Sys Roll one doesn't make sense and I am too lazy to understand and calculate it out. Can someone else do it please?
