When I can't remember an integral I usually just query wolfram and have it show steps. The first thing to realize is that, as long as our dice are fair, the actual numbers in the sequence are irrelevant: we would get the exact same probability for rolling [1, 2, 2 . MAS140_Sem2_W1.pdf. The coefficient of x k is the desired a k, and the probabilities are a k / 36. In Bayesian probability theory, if the posterior distribution p( | x) is in the same probability distribution family as the prior probability distribution p(), the prior and posterior are then called conjugate distributions, and the prior is called a conjugate prior for the likelihood function p(x | )..
