Has anyone done a probability matrix to determine the odds of rolling the possible outcomes on various mixes of dice? I know its fairly straight forward (if you are any good at maths) of working out the odds of rolling certain results (Blank/Triumphs, no Advantage etc), on positive dice, but I have no idea how to work out the odds of a "successful roll when you roll X Yellow, X Green and X. Probability, Expected Payoffs and Expected Utility the basic rules of probability and then derive the notion of expected value. = d / (c+d) Positive likelihood ratio: ratio between the probability of a positive test result given the presence of the disease and the probability of a positive test result given the absence of the disease, i. Converting odds is pretty simple. This means that there is a 95% probability that the true linear regression line of the population will lie within the confidence interval of the regression line calculated from the sample data. When trying to calculate the probabilities exactly using the Markov matrix, it is necessary to estimate the probability--for each square--that the last two rolls of the dice are doubles (since three doubles in a row sends you to jail).
