deduced from analysis of possible outcomes. Also called Classical or A Priori probability.
probability of A = number of times A can occur / number of possible outcomes P(A) = n(A)/p(A) ** The difference between Theoretical vs Empirical is that Theoretical should be 100% accurate since it is not dependant on trials, it calculates ALL outcomes**
Tree diagrams
You can use tree diagrams to find out different results for theoretical probability. A sort of brute force method to finding probability
