WebExpectation Given X = p, the conditional distribution of S n is binomial ( n, p). Therefore E ( S n ∣ X = p) = n p or, equivalently, E ( S n ∣ X) = n X By iteration, E ( S n) = E ( n X) = n E ( X) = n r r + s The expected proportion of heads in n tosses is E ( S n n) = r r + s which is the expectation of the prior distribution of X.
