Let $X$ be the number of packets that fail to reach their destination nodes from $n$ = 100 randomly selected packets. Use the Beta-binomial formulation to specify the posterior distribution $p(\theta|n,X)$, where $\theta$ (theta) is the probability of a packet failing to reach the destination node. Specify explicitly all the probability density functions of the model and state how the corresponding expected values are calculated.
This is what I got for now:
This doesn't make sense because $p(n)$ shouldn't have a value. Can someone tell me where to go or what am I doing wrong? I understand that the posterior should be a Beta Distribution.
