Suppose we're going to flip a coin 3 times, and we assign the same prior probability to each possible number of heads. For example: .Pr(2 heads) = Pr(1 head) We also assign the same prior probability to any two sequences that have the same number of heads. For example: . Pr(H, & H2 & T3) = Pr(T1 & H2 & H3) What is Pr(H2 | H1)
